4.2 Self-check Board Recovery
Perform the following steps to recover in cases where the integrated debugger or the OCD Checker operate
abnormally, such as when the self-check board's embedded ID code is uncertain, or when an area (at address 0x84)
reserved for use by the QB-78K0MINI has been set as a use-prohibited area.
(1) Connect the flash programmer to the self-check board.
Figure 4-2 shows the connection between the flash programmer and the self-check board (FP1 connector).
It is assumed that a PG-FP4 target cable (type A) is used to connect on the flash programmer side.

Recommended settings for programmer
Target operating voltage: 5 V (supplied from programmer)
Target operating frequency: 10 MHz (supplied from programmer)
Write ports: 3-wire handshake mode or 3-wire (SIO-ch0) mode
Serial transfer rate: 625 kHz
Cautions 1. To avoid signal conflicts, do not connect the flash programmer to the QB-78K0MINI.
2. When connecting the flash programmer, connect the programmer's cable to the FP1
connector. Board faults may occur if this cable is attached to a different connector.
