PIC32MX FAMILY
Cell Transfer: The number of bytes transferred when
a DMA channel has a transfer initiated before waiting
for another event (given by the DCHCSIZ register). A
cell transfer comprises one or more transactions.
Block Transfer: Defined as the number of bytes trans-
ferred when a channel is enabled. The number of bytes
is the larger of either DCHxSSIZ or DCHxDSIZ. A block
transfer comprises one or more cell transfers.

The mode is enabled by clearing the CHXM bit
(DCHxCON<3>).
Normal Addressing mode transfer features:
• In Normal Addressing mode, the transfer size is
• The Source and Destination Pointers wrap around
• A block transfer is complete when the block size
• A DMA event will transfer cell size (DCHxCSIZ)
10.3.1
Microchip recommends taking the following steps to
configure a DMA transfer in Normal Addressing mode:
• Disable the DMA channel interrupts in the INT
• Clear any existing channel interrupt flags in the
• Enable the DMA controller (if not already
• Set Channel Control register: Priority,
• Set the channel event control: clear/set the events
• If using a pattern match, set the pattern in the
• Set the transfer source and destination physical
• Set the source and destination sizes (DCHxSSIZ,
• Set the cell transfer size (DCHxCSIZ).
• Clear any existing event flag in the DCHxINT
