Dedicated output pins
The output states are determined by BO1 to BO5 in the
serial data.
Data: 0 = open, 1 = low
These pins go to the open state after the power on reset.
An 8 Hz time base signal can be output from BO1 when
TBC in the serial data is set to 1.
Note that the ON impedance of the BO1 pin is higher
than that of the other pins (BO2 to BO5).
Pins used for both input and output
The input or output state is determined by bits IOC1 and
IOC2 in the serial data.
Data: 0 = input port, 1 = output port
When specified for use as an input port:
The input state is transmitted to the controller through
the DO pin.
Input state: Low
→ data value = 0
High
→ data value = 1
When specified for use as an output port:
The output state is determined by bits IO1 and IO2 in the
serial data.
Data: 0 = open, 1 = low
These pins go to the input port state after the 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 will be output from the PD pin.
Similarly, when that frequency is lower, a low level will
be output. The PD pin goes to the high impedance state
when the frequencies agree.
The MOS transistor used for the PLL active low-pass
filter.
The input frequency range is from 0.4 to 12 MHz.
The signal is supplied directly to the IF counter.
The result from the IF counter MSB is output through the
DO pin.
There are four measurement periods: 4, 8, 32, or 64 ms.
