change.
Some parametric limits are subject to
I/O PORTS
Direction Registers
The I/O ports P0–P8 have direction registers which determine the
input/output direction of each individual pin. Each bit in a direction
register corresponds to one pin, each pin can be set to be input port
or output port.
When “0” is written to the bit corresponding to a pin, that pin be-
comes an input pin. When “1” is written to that bit, that pin becomes
an output pin.
If data is read from a pin set to output, the value of the port output
latch is read, not the value of the pin itself. Pins set to input are float-
ing. If a pin set to input is written to, only the port output latch is
written to and the pin remains floating.
Slew Rate Control
By setting bits 0 to 5 of the port control register (address 0010
16
) to
“1”, slew rate control is enabled. VIHL or CMOS level can be used as
a port P2 input level; CMOS or TTL level can be used as an input
level of master CPU bus interface.
Pull-up Control
By setting the port P2 pull-up control register (address 0012
16
), pull-
up of each pin of port P2 can be controlled with a program.
However, the contents of port P2 pull-up control register do not affect
ports programmed as the output ports but as the input ports.

Notes 1
: The slew rate function can reduce di/dt by modifying an internal
buffer structure.
2
: The characteristics of VIHL level is basically the same as that of
TTL level. But, its switching center point is a little higher than
TTL
