Serial interfaces
Functional description
The STM32W108 has two serial controllers, SC1 and SC2, which provide several options
for full-duplex synchronous and asynchronous serial communications.

Receive and transmit FIFOs allow faster data speeds using byte-at-a-time interrupts. For the
highest SPI and UART speeds, dedicated receive and transmit DMA channels reduce CPU
loading and extend the allowable time to service a serial controller interrupt. Polled
operation is also possible using direct access to the serial data registers.
components of the serial controllers.
The notation SCx means that either SC1 or SC2 may be substituted to form the name of a
specific register or field within a register.
