- config ADC_FORCE_XPD_FSM
- bool "Use the FSM to control ADC power"
- default n
- help
- ADC power can be controlled by the FSM instead of software. This allows the ADC to
- be shut off when it is not working leading to lower power consumption. However
- using the FSM control ADC power will increase the noise of ADC.
- config ADC2_DISABLE_DAC
- bool "Disable DAC when ADC2 is used on GPIO 25 and 26"
- default y
- help
- If this is set, the ADC2 driver will disables the output of the DAC corresponding to the specified channel. This is the default value.
- For testing, disable this option so that we can measure the output of DAC by internal ADC.

- help
- Normally only the ISR of SPI master is placed in the IRAM, so that it
- can work without the flash when interrupt is triggered.
- For other functions, there's some possibility that the flash cache
- miss when running inside and out of SPI functions, which may increase
- the interval of SPI transactions.
- Enable this to put ``queue_trans``, ``get_trans_result`` and
- ``transmit`` functions into the IRAM to avoid possible cache miss.
- During unit test, this is enabled to measure the ideal case of api.
- config SPI_MASTER_ISR_IN_IRAM
- bool "Place SPI master ISR function into IRAM"
- default y
- help
- Place the SPI master ISR in to IRAM to avoid possibly cache miss, or
- being disabled during flash writing access.
