Description
Half-End Interrupt Enable
Specifies whether to issue an interrupt request to the
CPU when the transfer count reaches half of the
DMATCR value that was specified before transfer
starts.
When the HIE bit is set to 1, the DMAC requests an
interrupt to the CPU when the HE bit becomes 1.
0: Disables an interrupt to be issued when DMATCR
1: Enables an interrupt to be issued when DMATCR
Acknowledge Mode
Specifies whether DACK and TEND are output in data
read cycle or in data write cycle in dual address mode.
In single address mode, DACK and TEND are always
output regardless of the specification by this bit.
This bit is valid only in CHCR_0 to CHCR_3. This bit is
reserved in CHCR_4 to CHCR_7; it is always read as
0 and the write value should always be 0.
0: DACK and TEND output in read cycle (dual address
1: DACK and TEND output in write cycle (dual
Acknowledge Level
Specifies the DACK (acknowledge) signal output is
high active or low active.
This bit is valid only in CHCR_0 to CHCR_3. This bit is
reserved in CHCR_4 to CHCR_7; it is always read as
0 and the write value should always be 0.
0: Low-active output from DACK
1: High-active output from DACK
