Reference 3 Multi-period Lower Limit Fail Bit
f the device sets this bit to high, the input REF3 fails the multi-period lower limit check.
(See Table 11, “Multi-Period Hysteresis Limits” on page 41)
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 11, “Multi-Period Hysteresis Limits” on page 41)
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 10, “Values for Single Period Limits” on page 40)
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 10, “Values for Single Period Limits” on page 40)
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 11, “Multi-Period Hysteresis Limits” on page 41)
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 11, “Multi-Period Hysteresis Limits” on page 41)
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 10, “Values for Single Period Limits” on page 40)
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 10, “Values for Single Period Limits” on page 40)
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 11, “Multi-Period Hysteresis Limits” on page 41)
Reference 1 Multi-period Upper Limit Fail Bit
If the device sets this bit to high, the input REF1 fails the multi-period upper limit
check. (See Table 11, “Multi-Period Hysteresis Limits” on page 41)
Reference 1 Single Period Lower Limit Fail Bit
If the device sets this bit to high, the input REF1 fails the single-period lower limit
check. (See Table 10, “Values for Single Period Limits” on page 40)
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 10, “Values for Single Period Limits” on page 40)
