23.2.1.13 ROM_uDMAChannelSelectSecondary
Selects the secondary peripheral for a set of uDMA channels.
Prototype:
void
ROM_uDMAChannelSelectSecondary(uint32_t ui32SecPeriphs)
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_uDMAChannelSelectSecondary is a function pointer located at
ROM_UDMATABLE[17].
Parameters:
ui32SecPeriphs is the logical or of the uDMA channels for which to use the secondary pe-
ripheral, instead of the default peripheral.
Description:
This function is used to select the secondary peripheral assignment for a set of uDMA chan-
nels. By selecting the secondary peripheral assignment for a channel, the default peripheral
assignment is no longer available for that channel.
The parameter ui32SecPeriphs 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 secondary peripheral (marked
as _SEC_) is selected.
