NAME
DESCRIPTION
31:24
CPU ID
CPU ID + REV ID. Read only.
Identifies which CPU is used and defines the silicon revision of the CPU.
23:16
REVISION ID
CPU ID + REVISION ID (31:16) are combined for a value of:
0x0203
for C6713/13B
Control power-down modes. The values are always read as zero.

SAT
Saturate bit.
Set when any unit performs a saturate. This bit can be cleared only by the MVC instruction and can
be set only by a functional unit. The set by the a functional unit has priority over a clear (by the MVC
instruction) if they occur on the same cycle. The saturate bit is set one full cycle (one delay slot) after
a saturate occurs. This bit will not be modified by a conditional instruction whose condition is false.
8
EN
Endian bit. This bit is read-only.
Depicts the device endian mode.
0
=
Big Endian mode.
1
=
Little Endian mode [default].
Program Cache control mode.
L1D, Level 1 Program Cache
000/010 =
All other PCC values reserved.
Data Cache control mode.
L1D, Level 1 Data Cache
000/010 =
All other DCC values reserved
Previous GIE (global interrupt enable); saves the Global Interrupt Enable (GIE) when an interrupt is
taken. Allows for proper nesting of interrupts.
7:5
PCC
Cache Enabled / Cache accessed and updated on reads.
4:2
DCC
Cache Enabled / 2-Way Cache

GIE
Global interrupt enable bit.
Enables (1) or disables (0) all interrupts except the reset interrupt and NMI (nonmaskable interrupt).
0
1
=
=
Disables all interrupts (except the reset interrupt and NMI) [default]
Enables all interrupts (except the reset interrupt and NMI)
