Note: With IF input selected, the IF input amp goes off in PLL Off mode. To use the IF counter in PLL Off mode,
select as an input port (CMOS input).
Note: The input amp not selected by the IF 1/2 bit goes off. When the input amp is off, input is set to high
impedance.
(1)
IF Counter Auto Mode
When IF counter Auto mode is selected, the MANUAL bit is set to 0 and the gate time is set based
on the IF input frequency band to be measured. Setting the STA/STP bit to 1 starts the IF counter,
inputs the clock during the specified gate time, counts the number of input pulses, then completes. To
determine when the IF counter has finished counting, check the BUSY bit. Note that the OVER bit is
set to 1 if the count equals or exceeds 2
20
input pulses.
To measure the input frequency, load the F0 to F19 IF data when the BUSY and OVER bits are
both 0.
(2)
IF Counter Manual Mode
Use Manual mode to measure the frequency by controlling the gate time with an internal time base
(e.g., 10 Hz).
To enter Manual mode, set the MANUAL bit to 1. At this time the gate time setting is “don’t care”. To
start the count, set the
STP
STA/
bit to 1. Setting the
loads the data in binary format.
STP
STA/
bit to 0 terminates the count and

IF Counter Input and Division Setting
Intermediate frequency (IF) measuring is normally based on the frequency of a signal input to the
IFin1 or IFin2 input pins. These pins incorporate input amps and can be used for low-amplitude
operation. In addition, input to the IF counter can be set as below. Use the input in accordance with
the specifications.
