EDMA3_DRV_ChainOptions
This configuration structure is used to configure the interrupt (final
and intermediate) generation and chaining (final and intermediate)
options.
Member Description
tcchEn
Transfer complete chaining enable.
When enabled, the chained event register (CER/CERH) bit is set on final
chained transfer completion (upon completion of the final/last TR in the
PaRAM set). The bit (position) set in CER or CERH is the TCC value specified.
itcchEn
Intermediate transfer completion chaining enable.
When enabled, the chained event register (CER/CERH) bit is set on every
intermediate chained transfer completion (upon completion of every
intermediate TR in the PaRAM set, except the final TR in the PaRAM set). The
bit (position) set in CER or CERH is the TCC value specified.
tcintEn
Transfer complete interrupt enable.
When enabled, the interrupt pending register (IPR/IPRH) bit is set on transfer
completion (upon completion of the final TR in the PaRAM set). The bit
(position) set in IPR or IPRH is the TCC value specified. In order to generate a
completion interrupt to the CPU, the corresponding Interrupt Enable Register:
TCC (IER [TCC]/IERH [TCC]) bit must be set to 1.
itcintEn
Intermediate transfer completion interrupt enable.
When enabled, the interrupt pending register (IPR/IPRH) bit is set on every
intermediate transfer completion (upon completion of every intermediate TR
in the PaRAM set, except the final TR in the PaRAM set). The bit (position) set
in IPR or IPRH is the TCC value specified. In order to generate a completion
interrupt to the CPU, the corresponding Interrupt Enable Register: TCC
(IER[TCC]/IERH[TCC]) bit must be set to 1.
