PMPEN: Parallel Master Port Enable bit
1 = PMP enabled
0 = PMP disabled, no off-chip access performed
Unimplemented: Read as ‘0’
PSIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
ADRMUX1:ADRMUX0: Address/Data Multiplexing Selection bits
11 =Reserved
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 3 bits are multiplexed on
00 =Address and data appear on separate pins
PTBEEN: Byte Enable Port Enable bit (16-bit Master mode)
1 = PMBE port enabled
0 = PMBE port disabled
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
CSF1:CSF0: Chip Select Function bits
11 = Reserved
10 = PMCS1 functions as chip select
0x = PMCS1 functions as address bit 14
ALP: Address Latch Polarity bit
