Apply voltage of 5 V ± 10 % (typical) to V
CC
and AV
CC
, and 0 V to V
SS
.
Connected to V
SS
.
To enter the reset state, the reset input pin must be kept at a LOW for 2
μ
s or more (under
normal V
CC
conditions).
If more time is needed for the quartz-crystal oscillator to stabilize, this LOW condition should
be maintained for the required time.
This chip has an internal clock generating circuit. To control generating frequency, an exter-
nal 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
of P0
