Notes: • Following bits are not provided (read as 0, writing has no effect):

P40, P60, P64–P67, P80, P81, P90–P92, P120–P123, P151, P152, P154–P157, P170–P173, P176, P177, P222, P223,

P226, P227

• All ports are set for input mode upon exiting the reset state.

• P221 is an input-only port. Fix it to "0" when write.

• After switching from output mode to input mode in the Port Direction Register, or after setting port input enable (PIEN0) bit to

"1" (input enable), pin level can be read after 2BCLK period.
