* Reference manual (RM0008)
* Section 25.3.1: Slave select (NSS) pin management
*
* Hardware NSS management:
* - NSS output disabled: allows multimaster capability for devices operating
* in master mode.
* - NSS output enabled: used only when the device operates in master mode.
*
* Software NSS management:
* - External NSS pin remains free for other application uses.
