• Specifies the divisor used by the programmable dividers. This is a binary value with P15 as
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
• Data that selects the reference frequency (fref)
Note: PLL INHIBIT
• In this state, the programmable divider block and the IF counter block are stopped, FMIN,
• Measurement start data for the IF counter
• Determines the measurement time for the general-purpose counter.
