(2) Control mode
These are the timer output pins for 3-phase PWM inverter control.
This pin inputs a reference voltage to the A/D converter.
Connect this pin to V
This is the analog power supply pin of the A/D converter.
Keep this pin at the same voltage as the V
This is the ground pin of the A/D converter.
Keep this pin at the same voltage as the V
This pin inputs an active-low system reset signal.
These pins are used to connect a crystal resonator for system clock oscillation.
To supply an external clock, input the clock to X1 and input the inverted signal to X2.

In this mode, P64 to P67 function as control signal output pins (RD, WR, WAIT, and ASTB) in the external
memory expansion mode. The pins used as control signal output pins are automatically disconnected from
internal pull-up resistors.
Caution If the external wait state is not used in the external memory expansion mode, P66 can be used
