Bit 7: Phase Detector 2 Gain Enable (PD2EN). When this bit is set to 1, the T4 phase detector 2 is enabled and
the gain is determined by the input locking frequency. If the frequency is greater than 8kHz, the gain is set by the
PD2G field. If the frequency is less than or equal to 8kHz, the gain is set by the PD2G8K field in the T4CR2
register. See Section 7.7.5.
0 = Disable
1 = Enable
Bits 2 to 0: Phase Detector 2 Gain (PD2G[2:0]). This field specifies the gain of the T4 phase detector 2 when the
input frequency is greater than 8kHz. This value is only used if automatic gain selection is enabled by setting
PD2EN = 1. See Section 7.7.5.
