O-6
Output port
The LC72146 latches the OUT6 bit in the serial data and
outputs it from pin O-6.

O-7
Output port
The LC72146 latches the OUT7 bit in the serial data and
outputs it from pin O-7.
Outputs a time base signal (8 Hz) when TBC is set to 1.
Function after a power on reset: open circuit

General-purpose I/O ports
Output mode circuit type: complementary
Function after a power on reset: input port
Can be set up to function as output ports by bits I/O-4
and I/O-5 in the serial data sent from the controller.

PD0
PD1
Charge pump
output
PLL charge pump output pin
If the frequency generated by dividing the local oscillator
frequency by N is higher than the reference frequency, a
high level will be output from PD0, and if it is lower, a low
level will be output. PD0 goes to the high-impedance
state when the frequencies match.
PD1 operates identically.

Connections for the
low-pass filter
transistor
Connections to the n-channel MOS transistor used for
the PLL active low-pass filter.
A high-speed locking circuit can be formed by using
these pins with the built-in sub charge pump.
See the item on the structure of the charge pump for
details.

HCTR/I-6
General-purpose
counter
HCTR is selected when CTS1 is set to 1.
Input frequency range: 0.4 to 25 MHz
The signal is passed through a divide-by-two circuit and
then input to a general-purpose counter. This input also
supports an integrating count function.
The result is output from the DO output pin starting with
the MSB of the general-purpose counter.
See the item on the structure of the general-purpose
counter for details.
When the H/I-6 bit in the serial data is set to 0:
This pin functions as an input port, and the value input is
output from the DO pin.
