PIC32MX3XX/4XX
REGISTER 20-1: PMCON: PARALLEL PORT CONTROL REGISTER (CONTINUED)
bit 7-6
CSF<1:0>: Chip Select Function bits⁽¹⁾
11 = Reserved
10 = PMCS2 and PMCS1 function as Chip Select
01 = PMCS2 functions as Chip Select, PMCS1 functions as address bit 14
00 = PMCS2 and PMCS1 function as address bits 15 and 14
bit 5
ALP: Address Latch Polarity bit⁽¹⁾
1 = Active-high (PMALL and PMALH)
0 = Active-low (PMALL and PMALH)
bit 4
CS2P: Chip Select 1 Polarity bit⁽¹⁾
1 = Active-high (PMCS2)
0 = Active-low (PMCS2)
bit 3
CS1P: Chip Select 0 Polarity bit⁽¹⁾
1 = Active-high (PMCS1/PMCS)
0 = Active-low (PMCS1/PMCS)
bit 2
Reserved: Write ‘0’; ignore read
bit 1
WRSP: Write Strobe Polarity bit
For Slave modes and Master Mode 2 (PMMODE<9:8> = 00,01,10):
1 = Write Strobe active-high (PMWR)
0 = Write Strobe active-low (PMWR)
For Master Mode 1 (PMMODE<9:8> = 11):
1 = Enable strobe active-high (PMENB)
0 = Enable strobe active-low (PMENB)
bit 0
RDSP: Read Strobe Polarity bit
For Slave modes and Master Mode 2 (PMMODE<9:8> = 00,01,10):
1 = Read strobe active-high (PMRD)
0 = Read strobe active-low (PMRD)
For Master Mode 1 (PMMODE<9:8> = 11):
1 = Read/Write strobe active-high (PMRD/PMWR)
0 = Read/Write strobe active-low (PMRD/PMWR)
Note 1: These bits have no effect when their corresponding pins are used as address lines
