This register is only available on 44-pin devices.
These bits have no effect when their corresponding pins are used as address lines.
CSF<1:0>: Chip Select Function bits
11 = Reserved
10 = Chip select function is enabled and PMCS acts as chip select (in Master mode). Up to
01 = Reserved
00 = Chip select function is disabled (in Master mode). All 16 address bits can be generated.
ALP: Address Latch Polarity bit
1 = Active-high (PMALL and PMALH)
0 = Active-low (PMALL and PMALH)
Unimplemented: Maintain as ‘0’
CS1P: Chip Select Polarity bit
1 = Active-high (PMCS)
0 = Active-low (PMCS)
BEP: Byte Enable Polarity bit
1 = Byte enable is active-high (PMBE)
0 = Byte enable is active-low (PMBE)
WRSP: Write Strobe Polarity bit
For Slave modes and Master Mode 2 (PMMODEH<1:0> = 00,01,10):
1 = Write strobe is active-high (PMWR)
0 = Write strobe is active-low (PMWR)
For Master Mode 1 (PMMODEH<1:0> = 11):
1 = Enable strobe is active-high (PMENB)
0 = Enable strobe is active-low (PMENB)
RDSP: Read Strobe Polarity bit
For Slave modes and Master Mode 2 (PMMODEH<1:0> = 00,01,10):
1 = Read strobe is active-high (PMRD)
0 = Read strobe is active-low (PMRD)
For Master Mode 1 (PMMODEH<1:0> = 11):
1 = Read/write strobe is active-high (PMRD/PMWR)
0 = Read/write strobe is active-low (PMRD/PMWR)
