 Set the T16A5 channel for invoking the DMAC using DMASEL[1:0]/T16A_CTL

x

 register.

 

(Default: 0x0)

 

At initial reset, TRG_SEL

x

[1:0] in all channels are set to 0x0 (hardware trigger disabled). Note that software 

triggers are enabled regardless of the trigger source selected.

 

These trigger sources (causes of interrupt) are used in common for interrupt requests and DMAC invocation re-
quests. When interrupts due to the cause used for a trigger is enabled and the interrupt level is set to 1 or more, 
an interrupt is also generated simultaneously with the trigger for the DMAC. When an interrupt vector and han-
dler routine are located in IRAM, interrupt handling can be executed even during a DMA transfer. An instruc-
tion for accessing the transfer source/destination is not executed until the DMA transfer is completed. When 
only invoking the DMAC and not using an interrupt, set the interrupt enable bit to 0 (interrupt disabled).

DMA request generated during a DMA transfer

 

A low-priority DMA request generated during a DMA transfer is not accepted until the transfer currently being 
executed is completed (until the unit data transfer is completed in the single transfer mode or until the transfer 
counter reaches 0 in the successive transfer mode).

 

A DMA request for another high-priority channel that is generated during successive transfers in a channel is 
accepted after the transfer of the current data unit is completed. The current DMA transfer is suspended at that 
point, and is resumed after that high-priority DMA transfer generated later is completed.

DMA request when the channel is disabled to transfer

 

Triggers are disabled for a channel with the CHEN bit (D3/1st word) set to 0 (DMA transfer disabled). 

 

TRG

x

 for the channel will not be set.
