CS2 CS1 ADDR13 ADDR12 ADDR11 ADDR10 ADDR9 ADDR8
bit 15 bit 8
R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
ADDR7 ADDR6 ADDR5 ADDR4 ADDR3 ADDR2 ADDR1 ADDR0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15 CS2: Chip Select 2 bit
1 = Chip Select 2 is active
0 = Chip Select 2 is inactive (pin functions as PMA<15>)
bit 14 CS1: Chip Select 1 bit
1 = Chip Select 1 is active
0 = Chip Select 1 is inactive (pin functions as PMA<14>)
bit 13-0 ADDR<13:0>: Parallel Port Destination Address bits
Note 1: PMADDR and PMDOUT1 share the same physical register. The register functions as PMDOUT1 only in
Slave modes and as PMADDR only in Master modes.
