SRCADDR1 - DMA Channel Source Address 1
SRCADDR0 - DMA Channel Source Address 0
DESTADDR2 - DMA Channel Destination Address 2
DESTADDR1 - DMA Channel Destination Address 1
• Bit 7:0 - SRCADDR[23:16]: DMA Channel Source Address 2
These bits hold byte 2 of the 24-bits source address.
• Bit 7:0 - SRCADDR[15:8]: DMA Channel Source Address 1
These bits hold byte 1 of the 24-bits source address.
• Bit 7:0 - SRCADDR[7:0]: DMA Channel Source Address 0
These bits hold byte 0 of the 24-bits source address.
DESTADDR0, DESTADDR1 and DESTADDR2 represents the 24-bit value DESTADDR, which
is the DMA channel destination address. DESTADDR2 holds the most significant byte in the reg-
ister. DESTADDR may be automatically incremented or decremented based on settings in the
DESTDIR bits in
Reading and writing 24-bit values require special attention, for details refer to
”Accessing 24- and 32-bit Registers” on page
• Bit 7:0 - DESTADDR[23:16]: DMA Channel Destination Address 2
These bits hold byte 2 of the 24-bits source address.
