bit 0

Legend:

RC = Readable only bit. Cleared when read and the conversion cycle completes.

W = Writable bit

U = Unimplemented bit, read as 0

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

X = Bit is unknown

Read this register to determine the cause of an alert. For more details, see Section 4.10.3.

This register is cleared when read and another conversion cycle completes. If the condition that triggered the alert is

still present when the conversion cycle completes, the bit associated with that type of alert remains set.

The register updates without requiring a Refresh (any) command.

The overcurrent, undercurrent, overpower, overvoltage and undervoltage alerts are disabled by default. To enable

these alerts, set the corresponding bits in the ALERT_ENABLE register.

Note:

No alert shows up in the ALERT_STATUS register unless it is first enabled in the ALERT_ENABLE register.

bit 15:14

Unimplemented at this time. Always reads 0.

bit 13

RV: Status of the Fast Rising Voltage alert.

0b = Alert for Fast Rising Voltage is not triggered

1b = Alert for Fast Rising Voltage was triggered

bit 12

FV: Status of the Fast Falling Voltage alert.

0b = Alert for Fast Falling Voltage is not triggered

1b = Alert for Fast Falling Voltage was triggered

bit 11

RC: Status of the Fast Rising Current alert.

0b = Alert for Fast Rising Current is not triggered

1b = Alert for Fast Rising Current was triggered

bit 10

FC: Status of the Fast Falling Current alert.

0b = Alert for Fast Falling Current is not triggered

1b = Alert for Fast Falling Current was triggered

bit 9

OC: Status of the Overcurrent alert.

0b = Alert for Overcurrent is not triggered

1b = Alert for Overcurrent was triggered

bit 8

UC: Status of the Undercurrent alert.

0b = Alert for Undercurrent is not triggered

1b = Alert for Undercurrent was triggered

bit 7

OV: Status of the Overvoltage alert.

0b = Alert for Overvoltage is not triggered

1b = Alert for Overvoltage was triggered
