7
TINT1/DMAC1
This bit can be configured as either the timer1 interrupt flag/mask bit, or the DMA channel 1
interrupt flag/mask bit. The selection is made in the DMPREC register.
6
DMAC0
This bit can be configured as either reserved, or the DMA channel 0 interrupt flag/mask bit. The
selection is made in the DMPREC register.
