This is an 8-bit I/O port equivalent to P0. In single-chip mode, P57 in
this port outputs a divide-by-8 or divide-by-32 clock of XIN or a clock of
the same frequency as XCIN as selected by software.

This is an 8-bit I/O port equivalent to P0. When used for input in single-
chip, memory expansion, and microprocessor modes, the port can be
set to have or not have a pull-up resistor in units of four bits by
software. Pins in this port also function as UART0 and UART1 I/O pins
as selected by software.
This is an 8-bit I/O port equivalent to P6 (P70 and P71 are N channel
open-drain output). Pins in this port also function as timer A0–A2, or
UART2 I/O pins as selected by software.
This is an 8-bit I/O port equivalent to P6. Pins in this port also function
as, timer B1, B2 input pins, A-D converter extended input pins, or A-D
trigger input pins as selected by software.
This is an 8-bit I/O port equivalent to P6. Pins in this port also function
as A-D converter input pins as selected by software. Furthermore, P104
–P107 also function as input pins for the key input interrupt function.
WRL / WR,
WRH / BHE,
RD,
BCLK,
HLDA,
HOLD,
ALE,
RDY
Output WRL, WRH (WR and BHE), RD, BCLK, HLDA, and ALE
signals. WRL and WRH, and BHE and WR can be switched using
software control.
WRL, WRH, and RD selected
With a 16-bit external data bus, data is written to even addresses
when the WRL signal is “L” and to the odd addresses when the WRH
signal is “L”. Data is read when RD is “L”.
WR, BHE, and RD selected
Data is written when WR is “L”. Data is read when RD is “L”. Odd
addresses are accessed when BHE is “L”. Use this mode when using
an 8-bit external data bus.
While the input level at the HOLD pin is “L”, the microcomputer is
placed in the hold state. While in the hold state, HLDA outputs a “L”
level. ALE is used to latch the address. While the input level of the
RDY pin is “L”, the microcomputer is in the ready state.
P80 to P84, P86, and P87 are I/O ports with the same functions as P6.
Using software, they can be made to function as the I/O pins for the
input pins for external interrupts. P86 and P87 can be set using
software to function as the I/O pins for a sub clock generation
circuit. In this case, connect a quartz oscillator between P86 (XCOUT
pin) and P87 (XCIN pin). P85 is an input-only port that also functions
for NMI. The NMI interrupt is generated when the input at this pin
changes from “H” to “L”. The NMI function cannot be cancelled using
software. The pull-up cannot be set for this pin.
