Bit 3 CIO3 — Configuration bit for IO3. CIO3 configures I/O pin 3 (IO3) as an
input or as an output.
CIO3 = 0 IO3 is configured as an input. This is the default value at re-
set.
CIO3 = 1 IO3 is configured as an output.
Bit 2 CIO2 — Configuration bit for IO2. CIO2 configures I/O pin 2 (IO2) as an
input or as an output.
CIO2 = 0 IO2 is configured as an input. This is the default value at re-
set.
CIO2 = 1 IO2 is configured as an output.
Bit 1 CIO1 — Configuration bit for IO1. CIO1 configures I/O pin 1 (IO1) as an
input or as an output.
CIO1 = 0 IO1 is configured as an input. This is the default value at re-
set.
CIO1 = 1 IO1 is configured as an output.
Bit 0 CIO0 — Configuration bit for IO0. CIO0 configures I/O pin 0 (IO0) as an
input or as an output.
CIO0 = 0 IO0 is configured as an input. This is the default value at re-
set.
CIO0 = 1 IO0 is configured as an output.
