When the DMA is configured for two-byte word transfers, the DMAx I/O Address register
must contain an even numbered address.
DMA_IO—DMA on-chip peripheral control register address
This byte sets the low byte of the on-chip peripheral control register address on Register
File Page
The DMAx Address High register specifies the upper four bits of address for the Start/
Current and End Addresses of DMAx.
DMA_END_H—DMAx End Address High Nibble
These bits, used with the DMAx End Address Low register, form a 12-bit End Address.
The full 12-bit address is given by {DMA_END_H[3:0], DMA_END[7:0]}.
DMA_START_H—DMAx Start/Current Address High Nibble
These bits, used with the DMAx Start/Current Address Low register, form a 12-bit Start/
Current Address. The full 12-bit address is given by {DMA_START_H[3:0],
DMA_START[7:0]}.
