Targ et Preferences
If your model includes an C280x/C28x3x ADC block with the
Use DMA (with C28x3x) parameter enabled, disable the
same DMA channel here in the Target preferences block.
This parameter has no corresponding bit or register.
Data size
Select the size of the data bit transfer:
16 bit or 32 bit.
The DMA read/write data buses a re 32 bits wide. 32-bit
transfers have approximately twice the data throughput of
a 16-bit transfe r.
When providing D MA service to McBSP, set Data size to
16 bit.
The following parameters are based on a 16-bit w ord size.
If you set Data size to
32 bit, double the value of the
following parameters:
• Size: Burst
• Source: Burst step
• Source: Transfer step
• Source: Wrap step
• Destination: Burst step
• Destination: Transfer step
• Destination: Wrap step
Data size corresponds to bit 14 (DATASIZE) in the Mode
Register (MODE).
Note When you select Use DMA (with C28x3x) in the
C280x/C28x3x ADC block, this parameter is
16 bit.
