(6) Summary of Transfer Modes
(7) Address Change Options
settings.
CCRn respectively select address change directions for the Source Address Register (SARn) and
the Destination Address Register (DARn). While memory addresses can be programmed to
increment, decrement or remain constant, I/O addresses must be programmed to remain constant.
the source and destination addresses are incremented or decremented after each transfer. The bit
position can be bit 0, 4, 8, 12 or 16. Use of bit 0 is the regular increment/decrement mode in which
the address changes by 1, 2 or 4, according to the source or destination size. Two examples of how
other increment/decrement modes affect address changes are show below.
Transfer Request Edge/Level Address Mode
The DMAC can perform data transfers as follows according to the combination of mode
Address pointers can increment, decrement or remain constant. The SAC and DAC fields in the
The SACM and DACM fields in the DTCRn provide options to program bit positions at which
Example 1: When address bit 0 is selected in the SACM field and address bit 4 is selected in
Example 2: When address bit 8 is selected in the SACM field and address bit 0 is selected in
