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 is calculated as follows:

If BTCTRL.STEPSEL = 1:

D S T A D D R = D S T A D D R S T A R T + B T C N T • ( B E A T S I Z E + 1 )

If BTCTRL.STEPSEL = 0:

D S T A D D R = D S T A D D R S T A R T + B T C N T • ( B E A T S I Z E + 1 ) • 2 S T E P S I Z E

  • DSTADDRSTART 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
  • BEATSIZE is the configured number of bytes in a beat
  • STEPSIZE is the configured number of beats for each incrementation
