bit 4
CS2P: Chip Select 2 Polarity bit⁽¹⁾
1 = Active-high (PMCS2)
0 = Active-low (PMCS2)
bit 3
CS1P: Chip Select 1 Polarity bit⁽¹⁾
1 = Active-high (PMCS1/PMCS)
0 = Active-low (PMCS1/PMCS)
bit 2
BEP: Byte Enable Polarity bit
1 = Byte enable active-high (PMBE)
0 = Byte enable active-low (PMBE)
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.
Legend:
R = Readable bit
-n = Value at Reset
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = bit is unknown
