|
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.

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.

|
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.
