0x0A00
7
Soft reset exclude regmap
Resets device but retain programmed register values (default is not reset)
6
DCO power-down
Places DCO in deep sleep mode (default is not powered down)
5
SYSCLK power-down
Places SYSCLK input and PLL in deep sleep mode (default is not powered down)
4
Reference input power-down
Places reference clock inputs in deep sleep mode (default is not powered down)
3
TDC power-down
Places the time-to-digital converter in deep sleep mode (default is not powered down)
2
APLL power-down
Places the Output PLL in deep sleep mode (default is not powered down)
1
Clock dist power-down
Places the clock distribution outputs in deep sleep mode (default is not powered down)

6
User holdover
Forces the device into holdover mode (default is not forced holdover mode).
If a tuning word history is available, then the history tuning word specifies the DCO
output frequency. Otherwise, the free run frequency tuning word register specifies the
DCO output frequency.
The phase and frequency lock detectors are forced into the unlocked state.
5
User freerun
Forces the device into user free run mode (default is not forced user free run mode).
The free run frequency tuning word register specifies the DCO output frequency. When
the user freerun bit is set, it overrides the user holdover bit (Address 0x0A01, Bit 6).
