Digital Diagnostic Functions
A 2-wire serial interface provides user to contact with module. The memory space is arranged into a lower, single page, address space of
128 bytes and multiple upper address space pages. This structure permits timely access to addresses in the lower page, such as Interrupt
Flags and Monitors.
Less time critical time entries, such as serial ID information and threshold settings, are available with the Page Select function. The
interface address used is A0xh and is mainly used for time critical data like interrupt handling in order to enable a one-time-read for all
data related to an interrupt situation. After an interrupt, IntL, has been asserted, the host can read out the flag field to determine the
affected channel and type of flag.
