This register sets the N-Samples limit that specifies how many samples must exceed the threshold before triggering
an alert. The register is not reset until a conversion cycle is complete and the alert condition is cleared. After an alert
is cleared, the N-SAMPLES_LIMIT register is reset.
Note:
Disable alerts in the ALERT_ENABLE register before making changes to the N-SAMPLES_LIMIT register
to avoid false triggers.
bit 15:12
Unimplemented at this time. Always reads 0.
bit 11:10
N-SAMPLES_OPC[1:0]: Configure the number of consecutive samples that must exceed the set
threshold before triggering the Overpower Critical alert.
00b = 1 sample (default)
01b = 4 samples
10b = 8 samples
11b = 16 samples
bit 9:8
N-SAMPLES_OPW[1:0]: Configure the number of consecutive samples that must exceed the set
threshold before triggering the Overpower Warning alert.
00b = 1 sample (default)
01b = 4 samples
10b = 8 samples
11b = 16 samples
bit 7:6
N-SAMPLES_OC[1:0]: Configure the number of consecutive samples that must exceed the set
threshold before triggering the Overcurrent alert.
00b = 1 sample (default)
01b = 4 samples
10b = 8 samples
11b = 16 samples
bit 5:4
N-SAMPLES_UC[1:0]: Configure the number of consecutive samples that must exceed the set
threshold before triggering the Undercurrent alert.
00b = 1 sample (default)
01b = 4 samples
10b = 8 samples
11b = 16 samples
