|
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.

If this is set, the ADC2 driver will disable 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.

Place the CAN ISR in to IRAM. This will allow the ISR to avoid
|
|
cache misses, and also be able to run whilst the cache is disabled
|
|
(such as when writing to SPI Flash).
|
|
Note that if this option is enabled:
|
|
- Users should also set the ESP_INTR_FLAG_IRAM in the driver
|
|
configuration structure when installing the driver (see docs for
|
|
specifics).
|
|
- Alert logging (i.e., setting of the CAN_ALERT_AND_LOG flag)
|
|
will have no effect.
