Buttons Sw1-Sw7 (Jp: 1, 5, 6, 8, 10, 11, 25, 38) - Fujitsu MB91470 SERIES User Manual

Note:
While a reset signal is asserted the red Reset-LED (LED16) is lit.
During normal operation, this LED should be off.
If the reset LED is steadily on or blinks periodically, check the power supply input voltage
and the settings for the reset generation by UART as well as the jumpers JP23 and JP30.

4.7 Buttons SW1-SW7 (JP: 1, 5, 6, 8, 10, 11, 25, 38)

JP1, JP5, JP8, JP10, JP11, JP38
Six user push buttons SW1-SW6 can be connected to the microcontroller.
SW2 also serves as test button for the MCU DTTI function, which stops the
PWM output e.g. in case of an inverter fault.
JP6 Common interrupt for SW3-SW6: Eases up button event handling when the
buttons are used to control an application
JP25 External reset circuit and button SW7 can be connected to the microcontroller.
