Register writes aren't taking effect (ESP32 family)

[m-anti]

Hey everyone,

I need a extra pair of eyes on some TinyGo code for an ESP32-C6. I'm trying to enable the power detector (PWDET), but the bits never actually seem to get set in the register.

Here is what I currently have:

const (
	c6PwDetConfigReg          = uintptr(0x600A0810) // see soc/esp32c6/register/soc/reg_base.h
	c6PwDetSarPowerForceBit   = uint32(1 << 24)     // bits are defined in hal/esp32c6/include/hal/sar_ctrl_ll.h
	c6PwDetSarPowerControlBit = uint32(1 << 23)
)

   // code in a function
   // Enable PWDET see hal at: sar_ctrl_ll_set_power_mode_from_pwdet(SAR_CTRL_LL_POWER_ON);
   c6PwDetCfg := (*volatile.Register32)(unsafe.Pointer(c6PwDetConfigReg))
   c6PwDetCfg.SetBits(c6PwDetSarPowerForceBit)
   c6PwDetCfg.SetBits(c6PwDetSarPowerControlBit)

Has anyone run into silent register write failures like this on the ESP32? Any ideas on what I might be missing would be super helpful!
