15.2.5 Software Interrupt Generation Register (SWINTR)
Note 1. Only 1 can be written.
SWINT Bit (Software Interrupt Generation)
When 1 is written to the SWINT bit, the interrupt request register 027 (IR027) is set to 1.
If 1 is written to the SWINT bit when the DTC transfer request enable register 027 (DTCER027) is set to 0, an interrupt
to the CPU is generated.
If 1 is written to the SWINT bit when the DTC transfer request enable register 027 (DTCER027) is set to 1, a DTC
transfer request is issued.
