8.22 UNICOMM (UART/SPI/I2C)

UNICOMM is a highly flexible peripheral which can be configured as a UART, SPI, I2C-Controller or I2C-Target function. The user can select one of the serial interfaces before configuration and data transfer. The peripheral uses a common FIFO per instance to maximize the device capability based on the operating state. A serial peripheral group combines one or more UNICOMM for special functions like I2C loopback and is an optional configuration. Table 8-12 describes the grouping of UNICOMM, peripheral serial interfaces available and FIFO depth.
