Repeat Size End Interrupt Enable

Enables/disables a repeat size end interrupt request.

In repeat transfer mode, when the next transfer is

requested after completion of a 1-repeat-size data

transfer while this bit is set to 1, the DTE bit in DMDR is

cleared to 0. At this time, the ESIF bit in DMDR is set to

1 to indicate that a repeat size end interrupt is

requested. Even when the repeat area is not specified

(ARS1 = 1 and ARS0 = 0), a repeat size end interrupt

after a 1-block data transfer can be requested.

In addition, in block transfer mode, when the next

transfer is requested after 1-block data transfer while

this bit is set to 1, the DTE bit in DMDR is cleared to 0.

At this time, the ESIF bit in DMDR is set to 1 to indicate

that a repeat size end interrupt is requested.

0: Disables a repeat size end interrupt

1: Enables a repeat size end interrupt

R/W

Area Select 1 and 0

Specify the block area or repeat area in block or repeat

transfer mode.

00: Specify the block area or repeat area on the source

address

01: Specify the block area or repeat area on the

destination address

10: Do not specify the block area or repeat area

Source Address Update Mode 1 and 0

Select the update method of the source address

(DSAR). When DSAR is not specified as the transfer

source in single address mode, this bit is ignored.

00: Source address is fixed

01: Source address is updated by adding the offset

10: Source address is updated by adding 1, 2, or 4

according to the data access size

11: Source address is updated by subtracting 1, 2, or 4

according to the data access size
