Zarlink Semiconductor Inc.
The R[3:0] bits select the Reference Divider divide ratio. The ratio selected is not a simple binary power-of-two
value but through a lookup table, see Table 7- PLL Reference Divider Ratios.
This register controls test modes within the PLL. This should be programmed with the default settings.
2.2 RF Control Register
A single register controls RF programmability.
