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 12, “Multi-period Hysteresis Limits” on page 46)
R0FMU
R0FL
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 12, “Multi-period Hysteresis Limits” on page 46)
Reference 0 Single Period Lower Limit Fail Bit
If the device sets this bit to high, the input REF0 fails the single-period lower limit
check. (See Table 11, “Values for Single Period Limits” on page 45)
R0FU
Reference 0 Single Period Upper Limit Fail Bit
If the device sets this bit to high, the input REF0 fails the single-period upper limit
check. (See Table 11, “Values for Single Period Limits” on page 45)
