Chip ID Register
The Chip ID register is hard-wired to a hexadecimal value of $81. The
Petra MCECC sector can be given a software reset by writing a value of
$0F to this register. This write is terminated properly with TA∗ and sets
most internal registers to their default (power-up) state. Although writes of
any value other than $0F to this register are ignored, the MCECC sector
always terminates the cycles properly with TA∗.
Chip Revision Register
The Chip Revision register is hard-wired to reflect the revision level of the
Petra/MCECC ASIC. The current value of the register is $01. Although
writes to this register are ignored, the MCECC sector pair always
terminates the cycles properly with TA∗.
