TIME_OUT_VA
These bits determine a factor which has a relationship with a period in seconds. A phase lock alarm will be raised if the T0
selected input clock is not locked in T0 DPLL within this period. If the PH_ALARM_TIMEOUT bit (b5, 09H) is ‘1’, the
phase lock alarm will be cleared after this period (starting from when the alarm is raised). Refer to the description of the
TIME_OUT_VALUE[5:0] bits (b5~0, 08H).
00: 2 (default)
01: 4
10: 8
11: 16
These bits represent an unsigned integer. If the value in these bits is multiplied by the value in the MULTI_FACTOR[1:0]
bits (b7~6, 08H), a period in seconds will be gotten.
A phase lock alarm will be raised if the T0 selected input clock is not locked in T0 DPLL within this period. If the
PH_ALARM_TIMEOUT bit (b5, 09H) is ‘1’, the phase lock alarm will be cleared after this period (starting from when the
alarm is raised).
