Reference 3 Multi-period Lower Limit Fail Bit: If the device sets this bit to high, the
input REF3 fails the multi-period lower limit check. (see Table 13, “Multi-period
Hysteresis Limits” on page 48)
Reference 3 Multi-period Upper Limit Fail Bit: If the device sets this bit to high, the
input REF3 fails the multi-period upper limit check. (see Table 13, “Multi-period
Hysteresis Limits” on page 48)
Reference 3 Single Period Lower Limit Fail Bit: If the device sets this bit to high, the
input REF3 fails the single-period lower limit check. (see Table 13, “Multi-period
Hysteresis Limits” on page 48)
Reference 3 Single Period Upper Limit Fail Bit: If the device sets this bit to high, the
input REF3 fails the single-period upper limit check. (see Table 13, “Multi-period
Hysteresis Limits” on page 48)
Reference 2 Multi-period Lower Limit Fail Bit: If the device sets this bit to high, the
input REF2 fails the multi-period lower limit check. (see Table 13, “Multi-period
Hysteresis Limits” on page 48)
Reference 2 Multi-period Upper Limit Fail Bit: If the device sets this bit to high, the
input REF2 fails the multi-period upper limit check. (see Table 13, “Multi-period
Hysteresis Limits” on page 48)
Reference 2 Single Period Lower Limit Fail Bit: If the device sets this bit to high, the
input REF2 fails the single-period lower limit check. (see Table 11, “Values for Single
Period Limits” on page 46)
Reference 2 Single Period Upper Limit Fail Bit: If the device sets this bit to high, the
input REF2 fails the single-period upper limit check. (see Table 11, “Values for Single
Period Limits” on page 46)
Reference 1 Multi-period Lower Limit Fail Bit: If the device sets this bit to high, the
input REF1 fails the multi-period lower limit check. (see Table 13, “Multi-period
Hysteresis Limits” on page 48)
