FMIN
I
FM VCO (local oscillator) input.
This pin is selected with the PLL instruction CW1.
The input must be capacitor coupled.
Input is disabled in backup mode, in halt mode, after a reset, and in PLL stop mode.
57
AMIN
I
AM VCO (local oscillator) input.
This pin and the bandwidth are selected with the PLL instruction CW1.
The input must be capacitor coupled.
Input is disabled in backup mode, in halt mode, after a reset, and in PLL stop mode.
59
E0
O
The main charge pump output. When the local oscillator frequency divided by N is higher
than the reference frequency a high level is output, when lower, a low level is output, and
the pin is set to the high-impedance state when the frequencies match.
Output goes to the high-impedance state in backup mode, in halt mode, after a reset, and
in PLL stop mode.
