21.3.8
SIIER is a 16-bit readable/writable register that enables the issue of SIOF interrupts. When each
bit in this register is set to 1 and the corresponding bit in SISTR is set to 1, the SIOF issues an
interrupt.

Description
Transmit Data DMA Transfer Request Enable
Transmits an interrupt as an interrupt to the CPU/DMA
transfer request. The TDREQE bit can be set as transmit
interrupts.
0: Used as a CPU interrupt
1: Used as a DMA transfer request to the DMAC
Transmit Control Data Ready Enable
0: Disables interrupts due to transmit control data ready
1: Enables interrupts due to transmit control data ready
Transmit FIFO Empty Enable
0: Disables interrupts due to transmit FIFO empty
1: Enables interrupts due to transmit FIFO empty
Transmit Data Transfer Request Enable
0: Disables interrupts due to transmit data transfer
1: Enables interrupts due to transmit data transfer
Receive Data DMA Transfer Request Enable
Transmits an interrupt as an interrupt to the CPU/DMA
transfer request. The RDREQE bit can be set as receive
interrupts.
0: Used as a CPU interrupt
1: Used as a DMA transfer request to the DMAC
Receive Control Data Ready Enable
0: Disables interrupts due to receive control data ready
1: Enables interrupts due to receive control data ready
