Description
Reserved
This bit is always read 0. The write value should
always be 0.
DREQ Select Bit
DS selects the sampling method of the DREQ pin
that is used in external request mode is detection
in low level or at the falling edge.
This bit is only valid in CHCR_0 and CHCR_1.
Writing to this bit is invalid in CHCR_2 and
CHCR_3; 0 is read if this bit is read.
In channel 0 and 1, if an on-chip peripheral
module is specified as a transfer request source
or an auto request is specified, specification of
this bit is ignored and detection at the falling edge
is fixed except in an auto-request.
0: DREQ detected in low level
1: DREQ detected at falling edge
Transmit Mode
TM specifies the bus mode when transferring
data.
0: Cycle steal mode
1: Burst mode
Transmit Size Bits 1 and 0
TS1 and TS0 specify the size of data to be
transferred.
00: Byte size (8 bits)
01: Word size (16 bits)
10: Longword size (32 bits)
11: 16-byte unit (4 longword transfers)
Interrupt Enable Bit
Setting this bit to 1 generates an interrupt request
when data transfer end (TE = 1) by the count
specified in DMATCR.
0: Interrupt request is not generated even if data
1: Interrupt request is generated if data transfer
transfer ends by the specified count
ends by the specified count
