ET-BASE
AVR
ATmega64/128
r3
is
AVR
Board
Microcontroller from ATMEL that uses 64Pin MCU No.ATmega64
and No.ATmega128. It mainly emphasizes on using resources of
MCU on this Board ET-BASE AVR ATmega64/128 r3. I/O Pins are
externally connected to be Port PA, PB, PC, PD, PE, PF and
Port ET-CLCD; so, it is more convenient to connect, and
including Port for downloading program. Moreover, it adds
Circuit Line Driver RS-232 to increase the capability of RS232 Serial Port Communication easier and more convenient.

How to download HEX File into MCU
If user requires download HEX File into AVR MCU of
ATMEL through Serial Programming, it has to use ET-AVR ISP
or other ISP Programmers such as AVRISP of AMTEL. If using
ET-AVR ISP, it downloads HEX File through Parallel Port of
computer; moreover, it has to use with ET-CAP10P of ETT and
Software PonyProg200. This PonyProg2000 is the program to
download HEX File data into AVR CPU through Serial
Programming and is compatible with AVR Board from ETT well.
User can read more information about general use of program
from Help of Program by self. In this case, we will mention
about how to setup Program PonyProg2000 to use with AVR
Board from ETT; moreover, it is compatible with all AVR
Boards from ETT.

moreover, it is compatible with all AVR Boards from ETT.
Please be careful in using AVR CPU No.ATmega64/128,
there are many Fuse Bits internal structure of ATmega64/128
that are used to set conditional operations of CPU. Some
Fuse Bits have effect on Serial Programming Download; if
user sets these Fuse Bits wrongly, it is unable to program
any CPU by Serial Programming any more. In this case, user
needs to edit these Fuse Bits by Parallel Programmer
correctly first.

Meaning of Fuse Bits of ATmega64/128
If ticked [√] in front of any Fuse Bit, it means that it
sets the Fuse Bit to be “0” or it programs the Fuse Bit.
If did not tick [√] in front of any Fuse Bit, it means
that it sets the Fuse Bit to be “1” or it does not
program thee Fuse Bit.
Meaning of Fuse Bits of ATmega64/128 that has
effect on Serial Programming
•
•
•
•
SPIEN: It is Serial Programming Enable Bit and user
always sets this Fuse Bit because it is able to
download program into CPU through In-System Serial
Programming. Normally, this Fuse Bit has been set
from the factory and it cannot be erased or edited
by any Serial Programming Mode. If CPU has been
programmed by Parallel Programming, user does not
forget to set and program this Fuse Bit.
OCDEN and JTAGEN: Both bits are used in case of
debugging the operation of MCU, programming data
through JRTAG Interface, and it has to use with AVR
JTAG Debugger. If user does not use this operation,
it is unnecessary to choose both bits.
CKOPT: It is Oscillator Option Bit. If this Fuse Bit
has been programmed, it sets CPU to run at Frequency
16MHz; on the other hand, if this Fuse Bit has not
been programmed, it sets CPU to run at Frequency not
higher than 8MHz. If using with the standard Board
from ETT that uses XTAL to be the Frequency
Generator, user should program this Fuse Bit because
it makes CPU run at XTAL frequency in the range of
1.0MHz–16.0MHz.
CKSEL3…0: It is Select Clock Source Bit that is used
together to choose Generator and frequency range for
using with CPU. If using with standard Board of ETT,
it has to set the value as External Crystal 1.0MHz16.0MHz, otherwise it makes the operation of program
error. If user sets the Frequency Generator wrongly;
for example, if user sets the value as External
Clock or External RC Oscillator, it makes CPU cannot
work because it has not been connected with external
Signal Clock. So, it is unable to program CPU
through Serial Programming any more. User has to
edit Fuse Bit of the CPU correctly and it needs to
choose the Frequency Generator as External Crystal.

0100-0001
0000
Table shows how to choose Frequency Generator from Fuse Bit
CKSEL [3…0].
NOTE:
- Value “1”: It means that it does not program the Fuse Bit
and there is no any tick sign [√] in front of the Fuse
Bit.
- Value “0”: It means that it programs the Fuse Bit and
- Should program the Fuse Bit of CKOPT to run at the
Frequency 1.0MHz-16.00MHz
- Not allowed to program Fuse Bit of CKSEL[3..0] because it
makes the operation error. For example, if user programs
all Fuse Bits of CKSEL[3..0] as 0; after Program
PnonyProg2000 wrote this Fuse Bit into CPU completely, it
is unable to use CPU with ETT Board anymore; moreover, it
is unable to program and edit any new Fuse Bit into CPU
through Serial Programming because CPU is unable to work.
Remember, if user has programmed all Fuse Bit of
CKSEL[3..0] as “0”, it commands CPU to run with frequency
of External Clock, so it makes the Frequency Generator of
External Crystal stop running; in this case, CPU waits to
receive the External Clock only. However, ETT Board only
uses
Signal
Clock
from
Circuit
Crystal
(External
Crystal); so, if CPU cannot start running, it is unable
to program or edit any Fuse Bit for CPU correctly through
Serial Programming. It has to edit Fuse Bit of the CPU by
Parallel Programmer first and user can use CPU with
Serial Programming again.
- Set the Fuse Bit position of Lock[2…1] as required.
