Reset input
This is connected to V
SS
.
To enter the reset state, the reset input pin must be kept at a “L” for 2
μ
s or more (under
normal V
CC
conditions).
If more time is needed for the quartz-crystal oscillator to stabilize, this “L” condition should
be maintained for the required time.
This chip has an internal clock generating circuit. To control generating frequency, an
external ceramic resonator or a quartz-crystal oscillator is connected between pins X
IN
and
X
OUT
. If an external clock is used, the clock source should be connected to the X
IN
pin and
the X
OUT
pin should be left open.
Port P0 is an 8-bit I/O port with direction register allowing each I/O bit to be individually
programmed as input or output. At reset, this port is set to input mode. The output structure
is N-channel open-drain output. (See note)
