23.2.1.12 ROM_uDMAChannelSelectDefault
Selects the default peripheral for a set of uDMA channels.
Prototype:
void
ROM_uDMAChannelSelectDefault(uint32_t ui32DefPeriphs)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_UDMATABLE is an array of pointers located at ROM_APITABLE[17].
ROM_uDMAChannelSelectDefault is a function pointer located at ROM_UDMATABLE[18].
Parameters:
ui32DefPeriphs is the logical or of the uDMA channels for which to use the default peripheral,
instead of the secondary peripheral.
Description:
This function is used to select the default peripheral assignment for a set of uDMA channels.
The parameter ui32DefPeriphs can be the logical OR of any of the following macros. If one of
the macros below is in the list passed to this function, then the default peripheral (marked as
_DEF_) is selected.
