Bits 31:4 Reserved, must be kept at reset value.
Bits 3:0 OF[3:0]: Trigger overrun event flag
The flag is set when a new trigger event occurs on DMA request generator channel x, before
the request counter underrun (the internal request counter programmed via the GNBREQ
field of the DMAMUX_RGxCR register).
The flag is cleared by writing 1 to the corresponding COFx bit in the DMAMUX_RGCFR
register.
