Function
Apply voltage of 3.0 V–5.5 V to VCC, and 0 V to VSS.
(Extended operating temperature version : 4.0 V to 5.5 V)
This pin controls the operation mode of the chip.
Normally connected to VSS.
If this pin is connected to VCC, the internal ROM is inhibited and external memory is accessed.
Reference voltage input pin for A-D and D-A converters
GND input pin for A-D and D-A converters
Connect to VSS.
Reset input pin for active “L”
Input and output signals for the clock generating circuit.
Connect a ceramic resonator or quartz-crystal oscillator between the XIN and XOUT pins to set the
oscillation frequency.
If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open.
The clock is used as the oscillating source of system clock.
8 bit CMOS I/O port
I/O direction register allows each pin to be individually programmed as either input or output.
At reset this port is set to input mode.
In modes other than single-chip, these pins are used as address, data, and control bus I/O pins.
