Data
SCC1: Receive Data
Supported by SCC1. SCC1 receives serial data from RXD.
DMA: Data Request Acknowledge 1
DACK1, DREQ1, DRACK1, and DONE1 belong to the SIU
DMA. DONE1 and DRACK1 are signals on the same pin and
therefore cannot be used simultaneously. There are two sets of
DMA pins associated with the PIO ports.
DMA: Done 1
DACK1, DREQ1, DRACK1, and DONE1 belong to the SIU
DMA. DONE1 and DRACK1 are signals on the same pin and
therefore cannot be used simultaneously. There are two sets of
DMA pins associated with the PIO ports.
SCC1: Transmit Data
Supported by SCC1. SCC1 transmits serial data out of TXD.
DMA: Data Request Acknowledge 2
DACK2, DREQ2, DRACK2, and DONE2 belong to the SIU
DMA. DONE2 and DRACK2 are signals on the same pin and
therefore cannot be used simultaneously. There are two sets of
DMA pins associated with the PIO ports.
DMA: Done 2
DACK2, DREQ2, DRACK2, and DONE2 belong to the SIU
DMA. DONE2 and DRACK2 are signals on the same pin and
therefore cannot be used simultaneously. There are two sets of
DMA pins associated with the PIO ports.
