Legend:
R = Readable bit
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 15-8
Unimplemented:
Read as ‘0’
bit 7-6
ANSA<7:6>:
Analog Function Selection bits
1
= Pin is configured in Analog mode; I/O port read is disabled
0
= Pin is configured in Digital mode; I/O port read is enabled
bit 5-0
Unimplemented:
Read as ‘0’
Note 1:
These bits are not available in 64-pin and 80-pin devices.
