Bit
Name
Description
7
T0_OPERATING_MODE
This bit indicates the operating mode switch for T0 DPLL; i.e., whether the value in the
T0_DPLL_OPERATING_MODE[2:0] bits (b2~0, 52H) changes.
0: Has not switched. (default)
1: Has switched.
This bit is cleared by writing a ‘1’.
6
T0_MAIN_REF_FAILED
This bit indicates whether the T0 selected input clock has failed. The T0 selected input clock fails when its validity
changes from ‘valid’ to ‘invalid’; i.e., when there is a transition from ‘1’ to ‘0’ on the corresponding INn bit (4AH, 4BH).
0: Has not failed. (default)
1: Has failed.
This bit is cleared by writing a ‘1’.
5 - 0
INn
This bit indicates the validity changes (from ‘valid’ to ‘invalid’ or from ‘invalid’ to ‘valid’) for the corresponding INn for T0
path, i.e., whether there is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the corresponding INn bit (b5~0, 4BH). Here n
is any one of 14 to 9.
0: Has not changed.
1: Has changed. (default)
This bit is cleared by writing a ‘1’.
