FS6510 Can't set IMPACT register

[Jamber_H]

After Power-On, the SBC is in Init mode, I set INIT_VAUX_OVUV_IMPACT register as 0xA, after 200us, I read back it, but the result is 0x0, which is not equal to the value I set. What's the reason?

Hi,

Please try to close the INIT_FS with at least 1 good WD refresh and then read back the INIT_VAUX_OVUV_IMPACT register.

Best regards,

Tomas

Hi, Tomas,

I tried that, I read this register periodly after I set it in INIT phase. In Normal phase, the value is not 0x0, but it's a default value as 0xE.
