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 11, “Multi-Period Hysteresis Limits” on page 41)
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 11, “Multi-Period Hysteresis Limits” on page 41)
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 10, “Values for Single Period Limits” on page 40)
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 10, “Values for Single Period Limits” on page 40)
Reference 3 Multi-period Lower Limit Mask Bit
When this bit is high, it masks the multi-period lower limit check (or forces pass) for
REF3.
Reference 3 Multi-period Upper Limit Mask Bit
When this bit is high, it masks the multi-period upper limit check (or forces pass) for
REF3.
Reference 3 Single-period Lower Limit Mask Bit
When this bit is high, it masks the single-period lower limit check (or forces pass) for
REF3.
Reference 3 Single-period Upper Limit Mask Bit
When this bit is high, it masks the single-period upper limit check (or forces pass) for
REF3.
