SYPCR controls the system monitors, SIU software watchdog period, and bus monitor timing.
The SYPCR is readable at any time but is writable only once after system hard reset.
PARTNUM
16–23
Part Number
This field is mask-programmed with a code corresponding to the part number of
the part on which the SIU is located. It helps factory test and user code that is
sensitive to part changes. This field changes when the part number changes. For
example, it would change if any new module is added or if the size of any memory
module changes. It does not change if the part is changed to fix a bug in an
existing module.
The MSC8113 part
number is 0x62.
MASKNUM
24–31
Mask Number
This field is mask-programmed with a code corresponding to the mask number of
the part on which the SIU is located. It helps factory test and user code that is
sensitive to part changes. It is programmed in a commonly changed layer and
should be changed for all mask set changes.
The MSC8113 initial
mask number is 0x00.

Software Watchdog Timer Count
Contains the count value for the SIU software watchdog
timer.

Bus Monitor Timing
Defines the time-out period for the bus monitor. The
granularity of this field is 8 bus clocks. (BMT = 0xFF is
translated to 0x7F8 clock cycles). BMT is used in both
the system and local bus monitors.
Note:
The value 0 is invalid; an error is generated for
each bus transaction.
