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 31-15 Unimplemented: Read as ‘0’
bit 15-14 PTEN14: PMCS1 Strobe Enable bits
1 = PMA14 functions as either PMA14 or PMCS1
(1)
0 = PMA14 functions as port I/O
bit 13-11 Unimplemented: Read as ‘0’
bit 10-2 PTEN<10:2>: PMP Address Port Enable bits
1 = PMA<10:2> function as PMP address lines
0 = PMA<10:2> function as port I/O
bit 1-0 PTEN<1:0>: PMALH/PMALL Strobe Enable bits
1 = PMA1 and PMA0 function as either PMA<1:0> or PMALH and PMALL
(2)
0 = PMA1 and PMA0 pads functions as port I/O
Note 1: The use of this pin as PMA14 or CS1 is selected by the CSF<1:0> bits in the PMCON register.
2: The use of these pins as PMA1/PMA0 or PMALH/PMALL depends on the Address/Data Multiplex mode
selected by bits ADRMUX<1:0> in the PMCON register.
