Hardware Control
The Hardware control is a subset of software control and it will only be briefly described with cross-referencing to
Software control programmable registers.
4.1.1
Control Pins
The ZL30402 has six dedicated control pins for selecting modes of operation and activating different functions.
These pins are listed below:
MS2 and MS1 pins: Mode Select: The MS2 (pin 19) and MS1 (pin 18) inputs select the PLL mode of operation.
See Table 1 for details. The logic level at these inputs is sampled by the rising edge of the F8o frame pulse.
FCS pin: Filter Characteristic Select. The FCS (pin 9) input is used to select the filtering characteristics of the
Core PLL. See Table 2 on page 19 for details.
