21.7.5.1 Source data end pointer
21.7.5.2 Destination data end pointer
The DMA channel control data structure must be programmed in the LPC122x’s SRAM
memory. The data structure must be aligned on a 256 byte boundary to create a
contiguous area for 21 channel control data structures and 21 alternate channel control
data structures. The base address of the primary channel control data structure in SRAM
must be between 0x1000 0000 and 0x1000 1F00 in increments of 0x100 (see
The pointer to the base address of the channel control data structure is programmed in
the CTRL_BASE_PTR register
Remark: The user memory (SRAM) is not accessed by the DMA controller unless the
channel is enabled and a transfer is started for this channel.
The src_data_end_ptr memory location contains a pointer to the end address of the
source data.
Before the controller can perform a DMA transfer, this memory location must be
programmed with the end address of the source data. The controller reads this memory
location when it starts a 2
counts down from the end address, and before each arbitration, the channel control data
structure is updated with the number of remaining transfers.
Remark: The controller does not write to this memory location.
Table 343. src_data_end_ptr bit assignments
The dst_data_end_ptr memory location contains a pointer to the end address of the
destination data.
Before the controller can perform a DMA transfer, this memory location must be
programmed with the end address of the destination data. The controller reads this
memory location when it starts a 2
control data structure is updated with the number of remaining transfers.
