Channel Exec Registers

(Ask a Question)

Each DMA channel contains a set of Exec registers which hold the information about the currently executing transfer. These registers are Read-Only and initialized when the Control.run bit is set. Upon initialization, all of the Next registers are copied into the Exec registers and a transfer begins. The status of the transfer can be monitored by reading the following Exec registers.

The base addresses of the above registers are listed in Table 1.
