TDA4VM: Does gpio write protection work properly in sdk7.3?

Part Number: TDA4VM

Dear Expert,

We configured A23 as wkup_gpio0_30
The verification result is normal
It can be pulled high and low
But when we verify the write protection, we find that the 4301D008 and 4301D00C registers are both 0x0
At the same time, we write 0x68EF3490 to 0x4301D008 and find that the read result is 68EF3491
Is there something wrong with the register we read?

thanks
