TC7 TC6 TC5 TC4 TC3 TC2 TC1 TR/M

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)

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.

R241 - Read/Write

Reset value: undefined

TRANSMITTER DMA ADDRESS POINTER

(TDAPR)

R243 - Read/Write

0

Reset value: undefined

RA7 RA6 RA5 RA4 RA3 RA2 RA1 RPS

7

0

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

address extension.

1: Select DMASR register for receiver DMA trans-

fers address extension.

TA7 TA6 TA5 TA4 TA3 TA2 TA1 TPS

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

address extension.

1: Select DMASR register for transmitter DMA

transfers address extension.
