PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
Each channel of the eight available channels has a control register that can select any of the device-level DMA sources as the final source for that corresponding channel. Table 6-36 lists the sources available for mapping to each channel, based on the value of the Source Configuration (SRCCFG) register. The DMA transfers are initiated upon rising edge of the selected DMA source.
SRCCFG = 0 | SRCCFG = 1 | SRCCFG = 2 | SRCCFG = 3 | SRCCFG = 4 | SRCCFG = 5 | SRCCFG = 6 | SRCCFG = 7 | |
