bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15

PMPEN: Parallel Master Port Enable bit

= PMP enabled

= PMP disabled, no off-chip access performed

bit 14

Unimplemented: Read as ‘0’

bit 13

PSIDL: Stop in Idle Mode bit

= Discontinue module operation when device enters Idle mode

= Continue module operation in Idle mode

bit 12-11

ADRMUX1:ADRMUX0: Address/Data Multiplexing Selection bits(1)

= Reserved

= All 16 bits of address are multiplexed on PMD<7:0> pins

= Lower 8 bits of address are multiplexed on PMD<7:0> pins, upper 3 bits are multiplexed on

PMA<10:8>

= Address and data appear on separate pins

bit 10

PTBEEN: Byte Enable Port Enable bit (16-bit Master mode)

= PMBE port enabled

= PMBE port disabled

bit 9

PTWREN: Write Enable Strobe Port Enable bit

= PMWR/PMENB port enabled

= PMWR/PMENB port disabled

bit 8

PTRDEN: Read/Write Strobe Port Enable bit

= PMRD/PMWR port enabled

= PMRD/PMWR port disabled

bit 7-6

CSF1:CSF0: Chip Select Function bits

= Reserved

= PMCS1 functions as chip select

= PMCS1 functions as address bit 14

bit 5

ALP: Address Latch Polarity bit(1)

= Active-high (PMALL and PMALH)

= Active-low (PMALL and PMALH)

bit 4

Unimplemented: Read as ‘0’

bit 3

CS1P: Chip Select 1 Polarity bit(1)

= Active-high (PMCS1/PMCS1)

=Active-low (PMCS1/PMCS1)

bit 2

BEP: Byte Enable Polarity bit

= Byte enable active-high (PMBE)

= Byte enable active-low (PMBE)

Note 1: These bits have no effect when their corresponding pins are used as address lines.
