PIC32MX1XX/2XX
bit 4
Unimplemented:
Read as ‘0’
bit 3
CS1P:
Chip Select 0 Polarity bit
(2)
1
= Active-high (PMCS1)
0
= Active-low (PMCS1)
bit 2
Unimplemented:
Read as ‘0’
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)
REGISTER 19-1:
PMCON: PARALLEL PORT CONTROL REGISTER (CONTINUED)
Note 1:
When using 1:1 PBCLK divisor, the user’s 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.
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.
