Default

Bit 7: Device Reset (RST).

When this bit is high the entire device is held in reset, and all register fields, except the

RST bit itself, are reset to their default states. When RST is active, the register fields with pin-programmed defaults

do not latch their values from the corresponding input pins. Instead these fields are reset to the default values that

were latched from the pins when the RST pin was last active. See section 7.11.

0 = Normal operation

1 = Reset

Bit 5: Frequency Range Detect Enable (FREN).

When this bit is high the frequency of each input clock is

measured and used to quickly declare the input inactive.

0 = Frequency Range Detect disabled

1 = Frequency Range Detect enabled

Bit 4: T0 DPLL LOCK Pin Enable (LOCKPIN).

When this bit is high the LOCK pin indicates when the T0 DPLL

state machine is in the LOCK state (OPSTATE.T0STATE=100).

0 = LOCK pin is not driven

1 = LOCK pin is driven high when the T0 DPLL is in the Lock state

Bits 2 to 0: T0 DPLL State Control (T0STATE[2:0]).

This field allows the T0 DPLL state machine to be forced to

a specified state. The state machine will remain in the forced state, and therefore cannot react to alarms and other

events, as long as T0STATE is not equal to 000. See section 7.7.1.

000 = Automatic (normal state machine operation)

001 = Free-run

010 = Holdover

011 = {unused value}

100 = Locked

101 = Pre-locked 2

110 = Pre-locked

111 = Loss-of-lock
