R1FU
Reference 1 Single Period Upper Limit Fail Bit:
If the device sets this bit to high, the
input REF1 fails the single-period upper limit check. (See Table 11, “Values for Single
Period Limits” on page 45)
3
R0FML
Reference 0 Multi-period Lower Limit Fail Bit:
If the device sets this bit to high, the
input REF0 fails the multi-period lower limit check. (See Table 13, “Default Multi-period
Hysteresis Limits” on page 47)
2
R0FMU
Reference 0 Multi-period Upper Limit Fail Bit:
If the device sets this bit to high, the
input REF0 fails the multi-period upper limit check. (See Table 13, “Default
Multi-period Hysteresis Limits” on page 47)
1
