DRV2667: Question of Software Behavior of the DRV2667 EVM

Part Number: DRV2667

Hi Sirs,

We found the MCU software of the DRV2667 EVM reads bit 0 of 0x02 register after vibration trigger events. 
(we converted the I2C analyzer's data format to PPC3's format) 

w b2 03 02
w b2 p4 00
w b2 02 01
r b2 02 01 -> returns 01
r b2 02 01 -> returns 01
r b2 02 01 -> returns 01
r b2 02 01 -> returns 01
r b2 02 01 -> returns 01
r b2 02 01 -> returns 00

is the 0x02 read back mandatory. Is there any impact if we ignore this step?
 


Thank you and Best regards,
