Microchip Technology 

PIC32MX1XX/2XX/5XX 64/100-PIN FAMILY

REGISTER 20-1: PMCON: PARALLEL PORT CONTROL REGISTER (CONTINUED)

bit 8

PTRDEN: Read/Write Strobe Port Enable bit

1 = PMRD/PMWR port enabled

0 = PMRD/PMWR port disabled

bit 7-6

bit 5

bit 4

bit 3

bit 2

bit 1

bit 0

CSF<1:0>: Chip Select Function bits(2)

11 = Reserved

10 = PMCS1 and PMCS2 function as Chip Select

01 = PMCS1 functions as address bit 14; PMCS2 functions as Chip Select

00 = PMCS1 and PMCS2 function as address bits 14 and 15, respectively

ALP: Address Latch Polarity bit(2)

1 = Active-high (PMALL and PMALH)

0 = Active-low (PMALL and PMALH)

CS2P: Chip Select 0 Polarity bit(2)

1 = Active-high (PMCS2)

0 = Active-low (PMCS2)

CS1P: Chip Select 0 Polarity bit(2)

1 = Active-high (PMCS1)

0 = Active-low (PMCS1)

Unimplemented: Read as ‘0’

WRSP: Write Strobe Polarity bit

For Slave Modes and Master mode 2 (MODE<1:0> = 00,01,10):

1 = Write strobe active-high (PMWR)

0 = Write strobe active-low (PMWR)

For Master mode 1 (MODE<1:0> = 11):

1 = Enable strobe active-high (PMENB)

0 = Enable strobe active-low (PMENB)

RDSP: Read Strobe Polarity bit

For Slave modes and Master mode 2 (MODE<1:0> = 00,01,10):

1 = Read Strobe active-high (PMRD)

0 = Read Strobe active-low (PMRD)

For Master mode 1 (MODE<1:0> = 11):

1 = Read/write strobe active-high (PMRD/PMWR)

0 = Read/write strobe active-low (PMRD/PMWR)

Note 1: When using 1:1 PBCLK divisor, the user software should not read/write the peripheral’s SFRs in the

SYSCLK cycle immediately following the instruction that clears the module’s ON control bit.

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