SSC1: Special Serial Connection bit 1
SSC1/SSC0:
01:Float the FW_RXD pin
10:Connect FW_RXD and FW_TXD to an
00:Connect B1 to ICH UART1
PCB: PCB version.
These bits define special connections between serial devices that are meaningless under normal operation. They are for development and/or manufacturing facilities. Leave these bits in their default state for normal operation.

HWMODE: Enables automatic switching by hardware
HO_LOS: Switch criteria in hardware (HW) mode.When set, use PLL holdover detection as the switch criteria.When cleared, use loss of clock (internal to PLD) as the switch criteria.
MS2/MS1: PLL Mode selection:
MS[2..1] = 00: Normal operation
MS[2..1] = 01: Holdover mode
MS[2..1] = 10:
MS[2..1] = 11: Reserved
REFALIGN: Reference clock phase alignment; changing this bit from 0 to 1 starts the alignment.
FCS: Filter characteristics of the PLL:
0:12 Hz filter without phase slope limitation
1:6 Hz filter with phase slope limited to 41 ns per 1.326 ms.
E3DS3/E3DS3OC3: These bits select the transmission clock frequency when TXREFx_SEL[2..0]=111 in telecom clock register 3.
E3DS3OC3 = 0, E3DS3 = 1: 8.592 MHz
E3DS3OC3 = 0, E3DS3 = 0: 11.184 MHz
E3DS3OC3 = 1, E3DS3 = 1: 34.368 MHz
E3DS3OC3 = 1, E3DS3 = 0: 44.736 MHz
