without via CPU.
between the SFR and internal RAM, and therefore, a large capacity of data can be processed. In addition, real-time
control using communication, timer, and A/D can also be realized.
16.1 Functions of DMA Controller
846
The 78K0R/Ix3 has an internal DMA (Direct Memory Access) controller.
Data can be automatically transferred between the peripheral hardware supporting DMA, SFRs, and internal RAM
As a result, the normal internal operation of the CPU and data transfer can be executed in parallel with transfer
Here are examples of functions using DMA.
Note
Number of DMA channels: 2
Transfer unit: 8 or 16 bits
Maximum transfer unit: 1024 times
Transfer type:
Transfer mode: Single-transfer mode
Transfer request: Selectable from the following peripheral hardware interrupts
• A/D converter
• Serial interface (CSI00
• Timer (channel 0, 1, 4, or 5)
Transfer target: Between SFR and internal RAM
• Successive transfer of serial interface
• Batch transfer of analog data
• Capturing A/D conversion result at fixed interval
• Capturing port value at fixed interval
44-pin and 48-pin products of 78K0R/IC3, 78K0R/ID3 and 78K0R/IE3 only.
2-cycle transfer (One transfer is processed in 2 clocks and the CPU stops during that
processing.)
