PMRSTM
Performance Monitor Reset Mask.
When set to 1,
the associated composite interrupt bit will be inhib-
ited (masked) from contributing to the interrupt pin
(INT).
Reserved.
These bits must be written to their reset
default value (111).
General-Purpose Interrupt Mask.
When set to 1,
the associated composite interrupt bits will be inhib-
ited (masked) from contributing to the interrupt pin
(INT).
UTOPIA Composite Interrupt Mask
. When set to
1, the associated composite interrupt bit will be
inhibited (masked) from contributing to the interrupt
pin (INT).
Data Engine Composite Interrupt Mask.
When
set to 1, the associated composite interrupt bit will
be inhibited (masked) from contributing to the inter-
rupt pin (INT).
Reserved.
These bits must be written to their reset
default value (1111).
Path Terminator Composite Interrupt Mask.
When set to 1, the associated composite interrupt
bit will be inhibited (masked) from contributing to
the interrupt pin (INT).
Overhead Processor Composite Interrupt Mask.
When set to 1, the associated composite interrupt
bit will be inhibited (masked) from contributing to
the interrupt pin (INT).

Performance Monitor Reset.
When this bit is set
to 1, the PMRST signal goes high. The register will
automatically be reset to 0, and the PMRST signal
will go low after 500 ms.
Reserved.
Software Reset.
When a binary value of 101 is
written to this register, it will create a software reset
of the device. This reset has the same effect as the
hardware reset. All microprocessor registers are
reset to their default states, and all internal data
path state machines are reset.
