Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-2
bit 1-0
PTEN7:PTEN2: PMP Address Port Enable bits
1 = PMA<7:2> function as PMP address lines
0 = PMA<7:2> function as port I/O
PTEN1:PTEN0: PMALH/PMALL Strobe Enable bits
1 = PMA1 and PMA0 function as either PMA<1:0> or PMALH and PMALL
0 = PMA1 and PMA0 pads functions as port I/O

IBF: Input Buffer Full Status bit
1 = All writable input buffer registers are full
0 = Some or all of the writable input buffer registers are empty
IBOV: Input Buffer Overflow Status bit
1 = A write attempt to a full input byte register occurred (must be cleared in software)
0 = No overflow occurred
Unimplemented: Read as ‘0’
IB3F:IB0F: Input Buffer Status Full bits
1 = Input buffer contains data that has not been read (reading buffer will clear this bit)
0 = Input buffer does not contain any unread data
