Figure 5–63. Receive DMA Count Registers

5.6.10 Transmit DMA Count Registers A, B

There are two sets of Transmit DMA Count Registers, one set for Transmit DMA Channel
A and one set for Transmit DMA Channel B. Each register set contains two registers, one
for the low byte (bits 7-0) and one for the high byte (bits 15-8) as shown in Figure 5-35.
These registers are read write.
