  • Page 44: Chapter 5 Restrictions

    CHAPTER 5 RESTRICTIONS The restrictions are described below. A delay period of about 50 µs from cancellation of a target reset (RESET_IN) to cancellation of a target device reset (RESET_OUT) (the period from when the target reset (RESET_IN) becomes low to when the target device reset (RESET_OUT) becomes high) is required for mode setting.
  • Page 45 CHAPTER 5 RESTRICTIONS Note Restriction on using the self-check board (1.0) for operation check. • There is a communication problem due to a bug in the microcontroller mounted on the self-check board when the QB-78K0MINI operates on the Ring-OSC. The debugger takes a measure to avoid this problem by forcibly switching to the main clock when a break occurs, and re-switches to the Ring-OSC when the program is executed.
