  • 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 • 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.

    (3) Values specified by linker option -go Among the reserved areas used by QB-78K0MINI, the following areas can be secured using the linker option -go. Addresses 0x02 and 0x03 (Size of program specified from address 0x8F) +1 Specify the -go option default value, 256, for the program size for on-chip debugging.
  • Page 47 Values other than 0x02 and 0x03 cannot be written to address 0x84. The processing is performed so that 0x00 (the value set to disable QB-78K0MINI connection) or any other illegal value is not written. When setting 0x00, use a flash memory programmer (such as PG-FP4).
  • Page 48 PD78F0148HD. In this case, cluster 0 (0000H to 0FFFH) includes the area described in (1) Reserved area used by QB-78K0MINI (a) Flash memory area, so data in these areas must be copied to cluster 1 (1000H to 1FFFH), that is, the area in which 1000H is added to the address.
