Description
I/O 4-bit I/O port.
1-bit and 4-bit read/write and test are possible.
Individual pins are software configurable as
input or output; Individual pins are software
configurable as open-drain or push-pull output;
Individual pull-up resistors are software
assignable; pull-up resistors are automatically
disabled for output pins.
I/O Same as port 0.
I/O Same as port 0 except that port 2 is not
configurable as n-channel open drain and is
configurable as analog input pin.
I/O 2-bit I/O port
