I/O DIRECTION REGISTER
Controls the direction of the data I/O.
When a bit is set, the corresponding pin becomes an
input. When a bit is clear, the corresponding pin
becomes an output.
REGISTER 1-1:
IODIR – I/O DIRECTION REGISTER
R/W-1

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 7-0
IO7:IO0: Controls the direction of data I/O <7:0>
1
= Pin is configured as an input
0
= Pin is configured as an output
