Description

ESIF

R/(W)*

Transfer Escape Interrupt Flag

Flag indicating that a transfer escape end interrupt

request has occurred before the transfer counter

becomes 0 and transfer escape has ended.

0: Transfer escape end interrupt request is not

generated

1: Transfer escape end interrupt request is generated

[Clearing conditions]

• Writing 1 to the DTE bit

• Writing 0 to ESIF while reading ESIF = 1

[Setting conditions]

• Transfer size error interrupt request is generated

• Repeat size end interrupt request is generated

• Extended repeat area overflow end interrupt request

is generated

DTIF

R/(W)*

Data Transfer Interrupt Flag

Flag indicating that a transfer end interrupt request has

occurred by the transfer counter.

0: Transfer end interrupt request is not generated by

the transfer counter

1: Transfer end interrupt request is generated by the

transfer counter

[Clearing conditions]

• Writing 1 to the DTE bit

• Writing 0 to DTIF while reading DTIF = 1

[Setting condition]

• When EDTCR becomes 0 and transfer has ended

DTSZ1

DTSZ0

R/W

Data Access Size 1 and 0

Selects the data access size.

00: Byte-size (8 bits)

01: Word-size (16 bits)

10: Longword-size (32 bits)

11: Setting prohibited
