Dedicated output pins
The output states are determined by BO1 to BO4 bits in
the serial data.
Data: 0 = open, 1 = low
A time base signal (8 Hz) can be output from the BO1
pin. (When the serial data TBC bit is set to 1.)
Care is required when using the BO1 pin, since it has a
higher on impedance than the other output ports (pins
BO2 to BO4).
The data = 0 (open) state is selected after the power-on
reset.
I/O dual-use pins
The direction (input or output) is determined by bits IOC1
and IOC2 in the serial data.
Data: 0 = input port, 1 = output port
When specified for use as input ports:
The state of the input pin is transmitted to the controller
over the DO pin.
Input state: low = 0 data value
high = 1 data value
When specified for use as output ports:
The output states are determined by the IO1 and IO2
bits in the serial data.
Data: 0 = open, 1 = low
These pins function as input pins following a power on
reset.
PLL charge pump output
When the frequency generated by dividing the local
oscillator frequency by N is higher than the reference
frequency, a high level is output from the PD pin.
Similarly, when that frequency is lower, a low level is
output. The PD pin goes to the high impedance state
when the frequencies match.
The n-channel MOS transistor used for the PLL active
low-pass filter.
Accepts an input in the frequency range 0.4 to 12 MHz.
The input signal is directly transmitted to the IF counter.
The result is output starting the MSB of the IF counter
using the DO pin.
Four measurement periods are supported: 4, 8, 32, and
64 ms.
