16-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
INPUT/OUTPUT PINS
Ports P1, P2, and P5 through P7 all have the direction register, and
each bit can be programmed for input or output. A pin becomes an
output pin when the corresponding bit of direction register is “1”, and
an input pin when it is “0”.
Also, each bit of the port P6 direction register can be cleared to “0”
by inputting a falling edge to pin P6OUTCUT or by executing instruc-
tions.
When a pin is programmed for output, the data is written to its port
latch and it is output to the output pin. When a pin is programmed for
output, the contents of the port latch is read instead of the value of
the pin. Accordingly, a previously output value can be read correctly
even when the output “H” voltage is lowered or the output “L” voltage
is raised owing to an external load, etc.
A pin programmed as an input pin is in the flooting state, and the
value input to the pin can be read. When a pin is programmed as an
input pin, the data is written only in the port latch and the pin remains
floating.
Each of Figures 76 and 77 shows the block diagram for each port
pin.
When using a port pin as an internal peripheral device’s input pin,
clear the corresponding port direction register’s bit to “0”. When us-
ing a port pin as an internal peripheral device’s output pin, the port
direction register’s bit may be “0” or “1”.
