Legend:
R = Readable bit
U = Unimplemented bit
W = Writable bit
P = Programmable bit
-n = Bit Value at POR: (‘0’, ‘1’, x = Unknown)
r = Reserved bit
bit 31-16
bit 15
bit 14
bit 13
bit 12-11
bit 10
bit 9
bit 8
Reserved: Write ‘0’; ignore read
ON: Parallel Master Port Enable bit
1 = PMP enabled
0 = PMP disabled, no off-chip access performed
FRZ: Freeze in Debug Exception Mode bit
1 = Freeze operation when CPU is in Debug Exception mode
0 = Continue operation when CPU is in Debug Exception mode
Note: FRZ is writable in Debug Exception mode only, it is forced to ‘0’ in normal mode.
SIDL: Stop in Idle Mode
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
ADRMUX1:ADRMUX0: Address/Data Multiplexing Selection bits
11 = All 16 bits of address are multiplexed on PMD<15:0> pins
10 = All 16 bits of address are multiplexed on PMD<7:0> pins
01 = Lower 8 bits of address are multiplexed on PMD<7:0> pins, upper 8 bits are on PMA<15:8>
00 = Address and data appear on separate pins
PMPTTL: PMP Module TTL Input Buffer Select bit
1 = PMP module uses TTL input buffers
0 = PMP module uses Schmitt input buffers
PTWREN: Write Enable Strobe Port Enable bit
1 = PMWR/PMENB port enabled
0 = PMWR/PMENB port disabled
PTRDEN: Read/Write Strobe Port Enable bit
1 = PMRD/PMWR port enabled
0 = PMRD/PMWR port disabled
Note 1: These bits have no effect when their corresponding pins are used as address lines
