SCK
Four types of interrupts: Transmit-data-empty, transmit-end, receive-data-full, and receive-
error interrupts are requested independently. The transmit-data-empty and receive-data-full
interrupts can start the direct memory access controller (DMAC)/data transfer controller
(DTC) to transfer data.
