ACKP
CSDIS: Chip Select x Disable bit
1 = Disable the Chip Select x functionality
0 = Enable the Chip Select x functionality
CSP: Chip Select x Polarity bit
1 = Active-high (PMCSx)
0 = Active-low (PMCSx)
CSPTEN: PMCSx Port Enable bit
1 = PMCSx port is enabled
0 = PMCSx port is disabled
BEP: Chip Select x Nibble/Byte Enable Polarity bit
1 = Nibble/Byte enable is active-high (PMBE0, PMBE1)
0 = Nibble/Byte enable is active-low (PMBE0, PMBE1)
Unimplemented: Read as ‘0’
WRSP: Chip Select x Write Strobe Polarity bit
For Slave modes and Master mode when SM = 0:
1 = Write strobe is active-high (PMWR)
0 = Write strobe is active-low (PMWR)
For Master mode when SM = 1:
1 = Enable strobe is active-high (PMENB)
0 = Enable strobe is active-low (PMENB)
RDSP: Chip Select x Read Strobe Polarity bit
For Slave modes and Master mode when SM = 0:
1 = Read strobe is active-high (PMRD)
0 = Read strobe is active-low (PMRD)
For Master mode when SM = 1:
1 = Read/write strobe is active-high (PMRD/PMWR)
0 = Read/Write strobe is active-low (PMRD/PMWR)
SM: Chip Select x Strobe Mode bit
1 = Read/write and enable strobes (PMRD/PMWR and PMENB)
0 = Read and write strobes (PMRD and PMWR)
ACKP: Chip Select x Acknowledge Polarity bit
1 = ACK is active-high (PMACK1)
0 = ACK is active-low (PMACK1)
PTSZ<1:0>: Chip Select x Port Size bits
11 = Reserved
10 = 16-bit port size (PMD<15:0>)
01 = 4-bit port size (PMD<3:0>)
00 = 8-bit port size (PMD<7:0>)
