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
ADRMUX<1:0>: Address/Data Multiplexing Selection bits(1)
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
PMA<10:8>
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 and PMCS2 function as chip select
01 = PMCS2 functions as chip select, PMCS1 functions as address bit 14
00 = PMCS1 and PMCS2 function as address bits 15 and 14
ALP: Address Latch Polarity bit(1)
1 = Active-high (PMALL and PMALH)
0 = Active-low (PMALL and PMALH)
CS2P: Chip Select 2 Polarity bit(1)
1 = Active-high (PMCS2/PMCS2)
0 = Active-low (PMCS2/PMCS2)
CS1P: Chip Select 1 Polarity bit(1)
1 = Active-high (PMCS1/PMCS1)
0 = Active-low (PMCS1/PMCS1)
Note 1: These bits have no effect when their corresponding pins are used as address lines.
