Function
This is an 8-bit I/O port equivalent to P0.
This is an 8-bit I/O port equivalent to P0.
This is an 8-bit I/O port equivalent to P0.
The same frequency as divide-by-8, 32 of XIN from
P57 or XCIN are output by program selecting.
This is an 8-bit I/O port equivalent to P0.
These pins function as I/O pin of UART0 and UART1
by selecting it by the program.
This is an 8-bit I/O port equivalent to P0 (P70 and P71
are N channel open-drain output). This port can function
as I/O pins for timers A0 to A3 when so selected in a
program.
Furthermore, P70 to P73 function as I/O pins of UART2,
P71 function as input pin of timer B5, and P74 and P75
function as I/O pin of multi-master I2C bus.
P80 to P84, P86, and P87 are I/O ports with the same
functions as P0. When selected by a program,
P80 to P81 function as I/O pins of timer A4, P82 to P84
function input pin of INT interrupt.
And, P84 also function as output pin for remote control.
