7.1
The chip includes a data transfer controller (DTC). The DTC can be activated for data transfer by
an interrupt or software.
7.1.1
The features of the DTC are:
• Transfer possible over any number of channels
• Selection of transfer modes
• Direct specification of 16-Mbyte address space possible
• Transfer can be set in byte or word units
• A CPU interrupt can be requested for the interrupt that activated the DTC
• Activation by software is possible
• Module stop mode can be set
⎯ Transfer information is stored in memory
⎯ One activation source can trigger a number of data transfers (chain transfer)
⎯ Chain transfer execution can be set after data transfer (when counter = 0)
⎯ Normal, repeat, and block transfer modes available
⎯ Incrementing, decrementing, and fixing of source and destination addresses can be selected
⎯ 24-bit transfer source and destination addresses can be specified
⎯ An interrupt request can be issued to the CPU after one data transfer ends
⎯ An interrupt request can be issued to the CPU after all the specified data transfers have
⎯ The initial setting enables DTC registers to be accessed. DTC operation is halted by setting
ended
module stop mode
