Section 9 Data Transfer Controller (DTC)
(This function is not available in the H8S/2695)
9.1 Overview
The H8S/2633 Series includes a data transfer controller (DTC). The DTC can be activated by an
interrupt or software, to transfer data.
9.1.1 Features
The features of the DTC are:
• Transfer possible over any number of channels
 Transfer information is stored in memory
 One activation source can trigger a number of data transfers (chain transfer)
• Wide range of transfer modes
 Normal, repeat, and block transfer modes available
 Incrementing, decrementing, and fixing of source and destination addresses can be selected
• Direct specification of 16-Mbyte address space possible
 24-bit transfer source and destination addresses can be specified
• Transfer can be set in byte or word units
• A CPU interrupt can be requested for the interrupt that activated the DTC
 An interrupt request can be issued to the CPU after one data transfer ends
 An interrupt request can be issued to the CPU after the specified data transfers have
completely ended
• Activation by software is possible
• Module stop mode can be set
 The initial setting enables DTC registers to be accessed. DTC operation is halted by setting
module stop mode
