Usage
Function
Pin circuit
General-purpose I/O ports.
The outputs are complementary output circuits.
After the power-on reset, these ports function as input ports.
The input/output state of these ports can be set using the I/O-4 and
I/O-5 bits in the serial data sent from the controller.

A/D converter input
The A/D converter is a 6-bit successive-approximation circuit.
See the item on the structure of the A/D converter for details.

PLL charge pump output
When the frequency created by dividing the local oscillator signal
frequency by N is higher than the reference frequency, a high level is
output from the PD pin. When lower, a low level is output. The PD pin
goes to the high-impedance state when the frequencies match.

PD
Charge pump output
HCTR is selected by setting CTS in the control data to 1.
Input frequency: 0.4 to 25 MHz
The signal is input to a divide-by-2 circuit and the result is input to a
general-purpose counter. This counter can also be used as an
integrating counter.
The counter value is output as the result of the count, MSB first, from
the DO pin.
See the item describing the structure of the general-purpose counter
for details.

HCTR

Output buffer for the crystal oscillator circuit
When XB in the serial data is set to 1, the output buffer operates and
the crystal oscillator signal (a pulse signal) is output.
When XB is 0, XBUF outputs a low level.
(After the power-on reset, XB is set to 0 and the output buffer is fixed
at the low level.)
