6. The DMAC transfer proceeds as follows:
Channel Enable in the Channel Status Register (DMAC_CHSR.ENABLE[n]) until it is
disabled, to detect when the transfer is complete. If the DMAC is not in Row 1, the next
step is performed.
a. If interrupts is un-masked (DMAC_EBCIMR.BTC[x] = ‘1’, where x is the channel
b. If the buffer complete interrupt is masked (DMAC_EBCIMR.BTC[x] = ‘1’, where x is

number) hardware sets the buffer complete interrupt when the buffer transfer has
completed. It then stalls until the STALLED[n] bit of DMAC_CHSR register is
cleared by software, writing ‘1’ to DMAC_CHER.KEEPON[n] bit where n is the
channel number. If the next buffer is to be the last buffer in the DMAC transfer, then
the buffer complete ISR (interrupt service routine) should clear the automatic mode
bit in the DMAC_CTRLBx.AUTO bit. This put the DMAC into Row 1 as shown in
