bq78350-R1 Safe Pin for SOV

Hi,

I'm not able to trigger the Safe pin for a SOV event.

I'm using the bq79630EVM with following configuration:

- PF_EN and SAFE_EN is set 

- SOV in Enable PF A is set (I've noticed that this bit is documented in the technical reference document, but in bqstudio it's marked as RSVD, why?)

- SOV Delay (SOV_D1, SOV_D0) is 00 --> 1s delay

- AFE SOV Threshold is set to 4250mV

The bq79630evm is connected by a dc power supply. When I increase the voltage (above 4250mV per cell) the SOV bit will be set in PF Status A+B, but the SAFE bit in Operation Status A will not change.

Btw: A SUV event will trigger the SAFE pin - I've tested this succesfully.

Could anyone help me with this problem?

Thanks,

Patrick
