Input

Power supply. Apply the same voltage to the VDD1 and VDD0 pins.

• When the CPU and peripheral functions are operating: 4.5 to 5.5 V

• When only the CPU is operating: 3.5 to 5.5 V

• When the clock is stopped: 2.2 to 5.5 V

Input for PLL local oscillation (VCO) frequency

• VCOH

• Active when VHF mode is selected by software. Otherwise, pulled

down.

• VCOL

• Active when HF or MW mode is selected by software. Otherwise,

pulled down.

Inputs to these pins are to be AC-amplified. Cut, therefore, the DC

components in the input signals by using capacitors.

Output from the charge pump of the PLL frequency synthesizer. The

result of phase comparison between the divided local oscillation fre-

quency and reference frequency is output.

Test input pin.

Be sure to connect it to GND.

Output for port 1D and BEEP

• P1D3-P1D0

• 4-bit I/O port

• Input/output can be specified bit by bit.

• BEEP1, BEEP0

• BEEP output

4-bit I/O port.

Input/output can be specified bit by bit.

4-bit I/O port.

Input/output can be specified in 4-bit units.
