3.13. LED INDICATOR (LED1 & LED2)

AR-B1320 provides 2 on-board LEDs. One is power LED and the other is user-defined status LED.

3.13.1. POWER LED (LED1)

This LED indicates VCC (+5V) power is supplied or not.

3.13.2. STATUS LED (LED2)

This LED is designed for the user to define. The square wave output pin of the RTC chip drives the LED. You can activate, inactivate, and change the flash rates just by programming the register of the RTC chip. Use different flash rates to indicate different status or operating modes. The I/O port address of index register is 70H and data register is 71h.

3.14. USING THE FLASH DISK

The AR-B1320 provides two 32-pin PLCC sockets, one 32-pin

JEDEC DIP socket, and 1 DiskOnModule socket. The two

32-pin PLCC sockets and 32-pin JEDEC DIP socket may be populated with up to 1.5MB flash disks. The 32-pin JEDEC

DIP socket supports DiskOnChip from 2MB to 144MB. The following table shows the combinations of the SSD and

DiskOnChip:
