Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

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(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 functions as chip select

0x = PMCS1 functions as address bit 14

ALP: Address Latch Polarity bit(2)

1 = Active-high (PMALL and PMALH)

0 = Active-low (PMALL and PMALH)

Unimplemented: Read as ‘0’

CS1P: Chip Select 1 Polarity bit(2)

1 = Active-high (PMCS1/PMCS1)

0 = Active-low (PMCS1/PMCS1)

Note 1: 28-pin devices do not have PMA<10:2>.

2: These bits have no effect when their corresponding pins are used as address lines.
