Overview
Specification
General-register machine
High-speed operation suitable for realtime control
Instruction set suitable for high-speed operation
Two CPU operating modes
Address space divided into 8 areas, with bus specifications settable
independently for each area
Choice of 8-bit or 16-bit access space for each area
2-state or 3-state access space can be designated for each area
Number of program wait states can be set for each area
Direct connection to burst ROM supported
Supports debugging functions by means of PC break interrupts
Two break channels
Can be activated by internal interrupt or software
Multiple transfers or multiple types of transfer possible for one activation
source
Transfer possible in repeat mode, block transfer mode, etc.
Request can be sent to CPU for interrupt that activated DTC
