Power up and enable the temperature monitor.

1b: Enable and power up temperature monitor
Strobes ADC for temperature measurement.
0b: Ok to read temperature
1b: Read temperature
NOTE: To strobe ADC, a rising edge should be provided by writing 1b,
then writing 0b to return to default state.
A read of these bits returns the temperature from the last write cycle
(to strobe_temp).

N/A
Latched loss of lock alarm status.
0b = normal operation
1b = loss of CDR/RCLK lock
NOTE: After a clear (Globctrl [0] = 1), this register is cleared and will
latch any new alarms that make a L to H transition, and set any pre-
existing alarm conditions to H.
