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, and IFIN 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.
I/O port specification data
IOC1, IOC2
Specifies the I/O direction for the bidirectional pins IO1 and IO2.
Data: 0 = input mode, 1 = output mode
Output port data
BO1 to BO4, IO1, IO2
Data that determines the output from the BO1 to BO4, IO1 and IO2 output ports
Data: 0 = open, 1 = low
The data = 0 (open) state is selected after the power-on reset.
