Bits 31:0 – DSTADDR[31:0] Transfer Destination Address

This bit field holds the block transfer destination address.

When destination address incrementation is disabled (BTCTRL.DSTINC = 0), DSTADDR corresponds to the last beat transfer address in the block transfer.

When destination address incrementation is enabled (BTCTRL.DSTINC = 1), DSTADDR must be set to the ending address and calculated as follows:

If BTCTRL.STEPSEL = 1:

DSTADDR = {DSTADDR}_{START} \cdot BTCNT + BiB

If BTCTRL.STEPSEL = 0:

DSTADDR = {DSTADDR}_{START} \cdot BTCNT + BiB \cdot 2^{STEPSIZE}

Where,

DSTADDR_START is the destination address of the first beat transfer in the block transfer
BTCNT is the initial number of beats remaining in the block transfer
BiB is the configured number of bytes in a beat, as controlled by the BEATSIZE bit field.
STEPSIZE is the configured number of beats for each incrementation
