No.
Control block/data
Functions
Related data
Programmable divider data Data that sets the programmable divider.
P0 to P15
A binary value in which P15 is the MSB. The LSB changes depending on
DVS and SNS. (
*
: don’t care)
Note: P0 to P3 are ignored when P4 is the LSB.
DVS, SNS
Selects the signal input pin (AMIN or FMIN) for the programmable divider, switches
the input frequency range. (
*
: don’t care)
Note: See the “Programmable Divider” item for more information.
Reference divider data
R0 to R3
Reference frequency (fref) selection data.
Note: PLL INHIBIT
The programmable divider block and the IF counter block are stopped, the FMIN,
AMIN, HCTR and LCTR pins are set to the pull-down state (ground), and the charge
pump goes to the high impedance state.
XS
Crystal resonator selection
XS = 0: 4.5 MHz
XS = 1: 7.2 MHz
The 7.2 MHz frequency is selected after the power-on reset.
IF counter control data
CTE
IF counter measurement start data
CTE = 1: Counter start
CTE = 0: Counter reset
GT0, GT1
Determines the IF counter measurement period.
IFS
Note: See the “IF Counter” item for more information.
IF counter selection data
LCTS
L/I1
Data that specifies the IF counter input pin (and mode).
LCTS = 0: HCTR, LCTS = 1: LCTR
L/I1 = 0: I1 (Input port), L/I1 = 1: LCTR (AM IF counter)
