13.3.3 DMA Low Address Limit Register

Note:

The LADDR[23:0] bits apply to data space only. SFR space outside the range from LADDR[23:0] to HADDR[23:0] is accessible by the DMA and will not result in an interrupt. Setting LADDR[23:0] to an address in SFR will, therefore, be ignored.

Bits 23:0 – LADDR[23:0] Low Limit Address bits⁽¹⁾

These bits specify the lower address limit. When the DMA module initiates a transaction beyond this limit, the associated channel interrupt occurs, ADRERR[1:0] is set to 01, and CHEN is cleared.
