19.12.17 Destination Software Transaction Request Register
Name:
Access Type:
Offset:
Reset Value:
A bit is assigned for each channel in this register. ReqDstReg[n] is ignored when software handshaking is not enabled for
the source of channel n.
A channel DST_REQ bit is written only if the corresponding channel write enable bit in the REQ_WE field is asserted on the
same System Bus write transfer.
• REQ_WE[11:8]: Request write enable
• DST_REQ[3:0]: Destination request
