Description
DREQ Level
DREQ Edge Select
These bits specify the sampling method of the DREQ
pin input and the sampling level.
These bits are valid only in CHCR_0 to CHCR_3.
These bits are reserved in CHCR_4 to CHCR_7; they
are always read as 0 and the write value should
always be 0.
If the transfer request source is specified as an on-
chip peripheral module or if an auto-request is
specified, the specification by these bits is ignored.
00: DREQ detected in low level
01: DREQ detected at falling edge
10: DREQ detected in high level
11: DREQ detected at rising edge
Transfer Bus Mode
Specifies the bus mode when DMA transfers data.
Note that the burst mode must not be selected when
TC = 0.
0: Cycle steal mode
1: Burst mode
Transfer Size
These bits specify the size of data to be transferred.
Select the size of data to be transferred when the
source or destination is an on-chip peripheral module
register of which transfer size is specified.
00: Byte unit
01: Word unit (two bytes)
10: Longword unit (four bytes)
11: 16-byte (four longword) unit
Interrupt Enable
Specifies whether or not an interrupt request is
generated to the CPU at the end of the DMA transfer.
Setting this bit to 1 generates an interrupt request
(DEI) to the CPU when TE bit is set to 1.
0: Disables an interrupt request
1: Enables an interrupt request
