No. Control block/data Description Related data

• Specifies the divisor used by the programmable dividers. This is a binary value with P15 as
the MSB. The LSB depends on DVS and SNS.

DVS SNS LSB Divisor setting (N) Actual divisor

1 * P0 272 to 65535 The actual setting times 2
0 1 P0 272 to 65535 The actual setting
0 0 P4 4 to 4095 The actual setting

Note: When P4 is the LSB, bits P0 to P3 are ignored.

• Selects the input signal (FMIN or AMIN) to the programmable divider and switches the input
frequency range.

Note: PLL INHIBIT

• In this state, the programmable divider block and the IF counter block are stopped, FMIN,
AMIN, and IFIN are pulled down (to ground), and the charge pump goes to the high­impedance state.
