Hello community,
I have one question about PMU_REG_1P0Dn register of i.MX7D.
section "5.4.5.2 Anadig 1.0V D Regulator Control Register" of Reference manual,
It have OVERRIDE bit in bit 31 of PMU_REG_1P0Dn register,
but the only explanation is the description of register bit field.
First of all, what purpose is OVERRIDE bit used for?
If OVERRIDE=1, the set voltage will be output from the LDO even though ENABLE_LINREG=0.
Is this correct behavior?
Best regards,
Ishii.

Hello,
Yes, it does. You could try to use memtool to read it.
Best regards.
Hello,
When OVERRIDE bitfield of PMU_REG_1P0Dn register is set, GPC will be able to modify PMU_REG_1P0Dn bitfields automatically.
ENABLE_LINREG will have the same behavior but, GPC can enable/disable regulator output.
Best regards.
Hello @JorgeCas ,
Thank you for your reply.
You say that
> GPC will be able to modify PMU_REG_1P0Dn bitfields automatically.
In this time, does PMU_REG_1P0Dn register value change and could it read from CPU?
