RX System emulator

Use the executable qemu-system-rx to simulate RX target (GDB simulator). This target emulated following devices.

• R5F562N8 MCU

  • On-chip memory (ROM 512KB, RAM 96KB)
  • Interrupt Control Unit (ICUa)
  • 8Bit Timer x 1CH (TMR0,1)
  • Compare Match Timer x 2CH (CMT0,1)
  • Serial Communication Interface x 1CH (SCI0)

• External memory 16MByte

Example of qemu-system-rx usage for RX is shown below:
