Bit 1—Transfer End Bit (TE): Set to 1 on completion of the number of data transfers specified
in DMATCR. At this time, if the IE bit is set to 1, an interrupt request is generated.
in DMATCR. At this time, if the IE bit is set to 1, an interrupt request is generated.
If data transfer ends due to an NMI interrupt, a DMAC address error, or clearing of the DE bit or
the DME bit in DMAOR before this bit is set to 1, this bit will not be set to 1. Even if the DE bit
is set to 1 while this bit is set to 1, transfer is not enabled.
the DME bit in DMAOR before this bit is set to 1, this bit will not be set to 1. Even if the DE bit
is set to 1 while this bit is set to 1, transfer is not enabled.
Bit 1: TE
Description
0
Data transfers specified in DMATCR not completed
(Initial value)
Clearing conditions: Writing 0 to TE after reading TE = 1
Power-on reset, manual reset
1
Data transfers specified in DMATCR completed
Bit 0—DMAC Enable Bit (DE): Enables operation of the corresponding channel.
Bit 0: DE
Description
0
Channel operation disabled
(Initial value)
1
Channel operation enabled
If an auto-request is specified (RS3 to RS0), transfer starts when this bit is set to 1. In an external
request or an internal module request, transfer starts when a transfer request is generated after this
bit is set to 1. Clearing this bit during transfer terminates the transfer.

bit is set to 1. Clearing this bit during transfer terminates the transfer.
Even if the DE bit is set, transfer is not enabled if the TE bit is 1, the DME bit in DMAOR is 0, or
the NMIF or AE bit in DMAOR is 1.
