7.15 DMA Controller
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.
The 78K0R/KF3 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.
Number of DMA channels: 2
Transfer unit: 8 or 16 bits
Maximum transfer unit: 1024 times
Transfer type: 2-cycle transfer (One transfer is processed in 2 clocks and the CPU stops during that
Transfer mode: Single-transfer mode
Transfer request: Selectable from the following peripheral hardware interrupts
• A/D converter
• Serial interface (CIS00, CSI01, CSI10, UART0, UART1, UART3, or IIC10)
• Timer (channel 0, 1, 4, or 5)
Subject to transfer: 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
