3.15. SPI Interfaces
*
The module provides three SPI interfaces. 2 SPI interfaces for master mode, 1 SPI interface for slave
mode. The SPI interfaces function is multiplexed from GPIOs.
SPIM0 and SPIM1 interfaces in master mode up to 25 MHz.
SPIS interface supports slave mode only, up to 25 MHz.
The power domain of the SPI interface is 1.8 V. A voltage-level translator should be used between the
module and the host if your application is equipped with a 3.3 V processor or device interface.
3.16. ADC Interfaces
*
The module provides two analog-to-digital converter (ADC) interfaces by default. The other two ADC
interfaces can be multiplexed from GPIOs.
To improve the accuracy of ADC voltage values, the traces of ADC should be surrounded with ground.
