Description

Digital supply voltage (5V)

Digital ground (0V)

Analog supply voltage (5V)

Analog ground (0V)

Bias output for LCD driver

Bias output for LCD driver

Bias output for LCD driver

Pins for connecting capacitors that generate bias

for the LCD driver.

Oscillation input pin on the OSC side:

Connect to a quartz oscillator (ceramic resonator),

or input external clock.

Oscillation output pin on the OSC side:

Connect to a quartz oscillator (ceramic resonator).

When external clock is input to the OSC0 pin, the

OSC1 pin should be kept open.

System reset input:

When this pin is set to the "L" level, the internal

status is initialized to start execution of

instructions from address 0040H. The input is

pulled up to VDD with an internal pull-up resistor.
