Micro Direct Memory Access (μDMA)
Alternate Memory Scatter-Gather
This value must be used in the alternate channel control data structure when the μDMA controller
operates in Memory Scatter-Gather mode.
Peripheral Scatter-Gather
This value must be used in the primary channel control data structure when the μDMA controller
operates in Peripheral Scatter-Gather mode. In this mode, the μDMA controller operates exactly
the same as in Memory Scatter-Gather mode, except that instead of performing the number of
transfers specified by the XFERSIZE field in the alternate control structure at one time, the
μDMA controller only performs the number of transfers specified by the ARBSIZE field per
trigger; see Basic mode for details. See “Peripheral Scatter-Gather” on page 367.
Alternate Peripheral Scatter-Gather
This value must be used in the alternate channel control data structure when the μDMA controller
operates in Peripheral Scatter-Gather mode.
