Data Transfer Controller (DTC)
The RX610 Group incorporates a data transfer controller (DTC).
The DTC is activated by an interrupt request and controls data transfer.
13.1
Overview
Table 13.1 lists the specifications of the DTC, and figure 13.1 shows a block diagram of the DTC.

Description
Transfer mode
•
Normal transfer mode
•
Repeat transfer mode
•
Block transfer mode
Transfer of arbitrary
channels
•
Data of multiple channels can be transferred on a single startup source (chain
transfer).
•
Execution of chain transfer after data transfer can be set.
Short-address mode/
Full-address mode
•
Transfer data is packed in 3 longwords (short-address mode) or in 4 longwords
(full-address mode).
•
In short-address mode, transfer source address and transfer destination address can
be specified with 24 bits, and a 16-Mbyte address space can be directly specified for
repeat transfer.
•
In full-address mode, transfer source address and transfer destination address can be
specified with 32 bits, and a 4-Gbyte address space can be directly specified for
normal transfer.
Data transfer units
•
Byte, word, or longword
Transfer of units that are not aligned with the corresponding boundary is possible.
However, see selection 11, Buses, for details on the allowable range for the transfer of
a word or longword unit for which an odd address is specified, or of a longword unit
with an address of the form 4n + 2 (n = 0, 1, 2 …).
Interrupt source
•
An interrupt request is output to the CPU after a single data transfer.
•
An interrupt request is output to the CPU after data transfer of specified volume.
