Notes
1) SBx optional connections when using QB-78K0MINI ICE (refer to document no. U17029EJ2V0UM00)
−
When QB-78K0MINI is used, the QB-78K0MINI in-circuit emulator (ICE) handles the RESET connection.
−
When QB-78K0MINI is not used, connect 2JP7.1 to 2JP7.2 (10-pin header) with a shorting jumper.
−
22SB24 can be used to permanently connect RESETB_KX to RESETB_QB.
2) X2_QB: X2_QB is a single-wire, bi-directional data input that can be X2 or P32 (refer to the QB-78K0MINI
User's Manual).
−
2SB25 connects X2_QB to P32.
−
2SB26 connects X2_QB to X2 (factory default).
3) X1_QB: X1_QB can be X1 or P31.
−
2SB27 connects X1_QB to X1.
−
2SB28 connects X1_QB to P31.
4) Motor speed measurement input
−
INTP1_PX, INTP2_PY or INTP3_PZ are signals from motor control I/O board.
−
These are the signals providing sensor (HALL or back-EMF detection) inputs.
−
The selected INTP_x signal is input to P53/TI000 (capture/compare register) of the on-chip timer for speed
measurement.
4.11 2JP7: QB-78K0MINI ICE Connector
2JP7 is provided for connection to the QB-78K0MINI ICE. When QB-78K0MINI is connected, the
MINICUBE controls the MCU's RESET line. When QB-78K0MINI is not connected, pins 1 and 2
of 2JP7 should be shorted to control the RESET from the on-board 2SW1 pushbutton or the MC-IO
board's pushbutton through the 100-pin 2P2 target connector. To connect pins 1 and 2 on 2JP7, it is
recommended to use a jumper block instead of SB×.
