CHiFRDA:
Channel i First (Current) Receive Descriptor Address Register
(i=3...0)
i = 3...0
The DMA controller writes the first/current address of the channel
specific receive descriptor chain to these registers, i.e. the address of the
receive descriptor, the DMA receive channel i is currently working on.
These registers are only valid, if the DMA controller is operating in Last
Descriptor Address Mode (bit CMODE set to ’1’ in register GMODE).
