are for output. Lower

5 bits can be specified External trigger input for A/D converter.

in 1-bit units.

(7 pins)

Connects a crystal for main clock oscillation. (When the clock is supplied

externally, input it to EXTAL and input an opposite phase clock to XTAL.)

System reset. Active at "L" level.

Positive power supply for A/D converter. (Must be the same voltage with

VDD)

Reference voltage input for A/D converter. (Must be the same voltage with

VDD)

GND for A/D converter.

Positive power supply.

(Connect both VDD pins to positive power supply.)

GND. (Connect all four Vss pins to GND.)

NC. (NC is used for FLASH EEPROM incorporated version.)
