Communication Processor Module
You can read any RAM at any time, but for proper serial interface operation you must not try
to write the current-route RAM. You can, however, read the serial interface status register
(SISTR) to find out which part of the RAM is the current-route RAM.
Besides knowing which RAM is the current-route RAM, you might need to know which entry
the time-slot assigner is currently using within the current-route RAM. This information is
provided in the SIRP register, which is described in detail in Section 16.7.5.6 Serial
Interface RAM Pointer Register . You can also externally connect one of the eight strobes
to an interrupt pin to generate an interrupt on a particular serial interface RAM entry starting
or ending execution by the time-slot assigner.
