FIFO Read Pointer for Channel 3.
Any write to this byte will clear/flush the FIFO of channel 3.
FIFO Read Pointer for Channel 2.
Any write to this byte will clear/flush the FIFO of channel 2.
FIFO Read Pointer for Channel 1.
Any write to this byte will clear/flush the FIFO of channel 1.
FIFO Read Pointer for Channel 0.
Any write to this byte will clear/flush the FIFO of channel 0.
39.6.2.23 FIFO Write Pointer (FIFOWP)
The FIFOWP contains the current FIFO write pointers. Any write to FWPCHx will clear/flush the FIFO
and datapath of this channel, including the read/write pointer and all the FIFO flags. Any 32-bit write to
the FIFOWP will clear/flush the entire datapath/pipeline of the SGM.
