Function
This is an 8-bit I/O port equivalent to P0.
______
_______
These pins output CS0–CS3 signals and A16–A19. CS0–CS3 are
chip select signals used to specify an access space. A16–A19 are 4
high-order address bits.
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.
________

signals. WRL and WRH, and BHE and WR can be switched using
software control.
________
_____
s 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”.
______
_______
_____
s 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.
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–A3,
timer B5 or UART2 I/O pins as selected by software.
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
timer A4 and 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.
This is an 8-bit I/O port equivalent to P6. Pins in this port also
function as SI/O 3, 4 I/O pins, timer B0–B4 input pins, D-A converter
output 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
funciton as A-D converter input pins. Furthermore, P104–P107 also
function as input pins for the key input interrupt function.
Note 1: In M30623(80-pin package), the following signals do not have the corresponding external pin.
_______
q P10/D8 to P14/D12, P15/D13/INT3 to P17/D15/INT5
_______
q P44/CS0 to P47/CS3
________
__
___
q P72/CLK2/TA1OUT/V, P73/CST2/RTS2/TA1IN/V, P74/TA2OUT/W, P75/TA2IN/W
q P91/TB1IN/SIN3
Note 2: The M16C/62T group is not guaranteed to operate in memory expansion and microprocessor modes.
