H8S/2427, H8S/2427R, H8S/2425 Group
This LSI incorporates the SPI flash memory serial interface (FSI) that supports communications
between this LSI and SPI flash memory. The FSI performs communications using the CPU of this
LSI as a master.
Figure 21.1 shows a block diagram of the FSI.
21.1
• Supports communications between this LSI and SPI flash memory
• Can operate as a master
• Transfer clock selectable from system clock φ, φ/2, φ/4, φ/8, φ/16, φ/32, φ/64, and φ/128
• Two interrupt sources: Transmit end and receive end interrupts
