Legend:

R = Readable bit

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

Write to this register to assign a specific alert signal to pin A0. ALERT0 function.

Any changes to this register become active after a Refresh (any) command is sent.

Note 1: For the SLOW_ALERT0 register to control the A0 pin, the pin must be programmed for the alert function

in the CONTROL register. For more details, see Section 4.10.1.

2: Ensure alerts are enabled in the ALERT_ENABLE register before routing the alerts to this pin.

3: Ensure alerts are disabled in the ALERT_ENABLE register before changing any limits to avoid false triggers.

bit 15:14

Unimplemented at this time. Always reads 0.
