SERIAL COMMUNICATIONS INTERFACE (Cont’d)
RECEIVER DMA COUNTER POINTER (RDCPR)
R240 - Read/Write
Reset value: undefined
Bit 7:1 = RC[7:1]: Receiver DMA Counter Pointer.
These bits contain the address of the receiver
DMA transaction counter in the Register File.
Bit 0 = RR/M: Receiver Register File/Memory Se-
lector .
0: Select Memory space as destination.
1: Select the Register File as destination.
RECEIVER DMA ADDRESS POINTER (RDAPR)
R241 - Read/Write
Reset value: undefined
Bit 7:1 = RA[7:1]: Receiver DMA Address Pointer.
These bits contain the address of the pointer (in
the Register File) of the receiver DMA data source.
Bit 0 = RPS: Receiver DMA Memory Pointer Se-
lector.
This bit is only significant if memory has been se-
lected for DMA transfers (RR/M = 0 in the RDCPR
register).
0: Select ISR register for receiver DMA transfers
1: Select DMASR register for receiver DMA trans-

TRANSMITTER DMA COUNTER POINTER
(TDCPR)
R242 - Read/Write
Reset value: undefined
Bit 7:1 = TC[7:1]: Transmitter DMA Counter Point-
er .
These bits contain the address of the transmitter
DMA transaction counter in the Register File.
Bit 0 = TR/M: Transmitter Register File/Memory
Selector .
0: Select Memory space as source.
1: Select the Register File as source.
TRANSMITTER DMA ADDRESS POINTER
(TDAPR)
R243 - Read/Write
Reset value: undefined
Bit 7:1 = TA[7:1]: Transmitter DMA Address Point-
er.
These bits contain the address of the pointer (in
the Register File) of the transmitter DMA data
source.
Bit 0 = TPS: Transmitter DMA Memory Pointer Se-
lector.
This bit is only significant if memory has been se-
lected for DMA transfers (TR/M = 0 in the TDCPR
register).
0: Select ISR register for transmitter DMA transfers
1: Select DMASR register for transmitter DMA
