Section 8 Data Transfer Controller (DTC)

8.1

Overview

The SH7040 Series has an on-chip data transfer controller (DTC), which is activated either by

interrupts or software and can perform data transfers.

8.1.1

Features

• Arbitrary channel number transfer setting possible

 Transfer information can be established for each interrupt source

 Transfer information stored in memory

 Multiple data transfers possible (chain transfers) for one activating source

• Address space: 32-bit addresses can be designated for both transfer source and destination

• Transfer devices

 Memory: On-chip ROM, on-chip RAM, external ROM, external RAM

 On-chip peripheral modules (excluding DMAC/DTC)

 Memory-mapped external devices

• Abundant transfer modes

 Can select between normal mode/repeat mode/block transfer mode

 Can select between increment/decrement/fixed for source/destination address

• Transfer units can be set as byte/word/longword

• Interrupts activating the DTC can be requested of the CPU

 Interrupt requests can be generated to the CPU after completion of a data transfer

 Interrupt requests generated to the CPU after completion of all designated data transfers

• Transfers can be activated by software
