PMPEN: Parallel Master Port Enable bit
1 = PMP module is enabled
0 = PMP module is disabled, no off-chip access is performed
Unimplemented: Read as ‘0’
PSIDL: PMP Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
ADRMUX<1:0>: Address/Data Multiplexing Selection bits
11 = Reserved
10 = All 16 bits of address are multiplexed on PMD<7:0> pins
01 = Lower eight bits of address are multiplexed on PMD<7:0> pins, upper eight bits are on PMA<15:8>
00 = Address and data appear on separate pins
PTBEEN: Byte Enable Port Enable bit (16-Bit Master mode)
1 = PMBE port is enabled
0 = PMBE port is disabled
PTWREN: Write Enable Strobe Port Enable bit
1 = PMWR/PMENB port is enabled
0 = PMWR/PMENB port is disabled
PTRDEN: Read/Write Strobe Port Enable bit
1 = PMRD/PMWR port is enabled
0 = PMRD/PMWR port is disabled
CSF<1:0>: 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 1 Polarity bit⁽¹⁾
1 = Active-high (PMCS2)
0 = Active-low (PMCS2)
Note 1: These bits have no effect when their corresponding pins are used as address lines.
2: PMCS1 applies to Master mode and PMCS applies to Slave mode.
