V850ES/Jx3H – Plug it!
3.2 SW2, RESET button
SW2 is the reset button. It activates the power on reset. Switch SW2 controls the reset input signal of the
V850ES/Jx3-H - Plug it!
microcontroller.
3.3 SW3, Switch (INTP12)
SW3 is a push button connecting VSS to external interrupt input INTP12 of the microcontroller. This is
equal to port ”P98/INTP12” of the 70F3760 device. The port may be programmed to generate the
external interrupt INTP12. The necessary initialization for this purpose is described in the user’s manual
of the 70F3760 device.
3.4 SW4, Switch (INTP13)
SW4 is a push button connecting VSS to external interrupt input INTP13 of the microcontroller. This is
equal to port ”P99/INTP13” of the 70F3760 device. The port may be programmed to generate the
external interrupt INTP13. The necessary initialization for this purpose is described in the user’s manual
of the 70F3760 device.
3.5 JP1 and JP2, Power Supply selectors
Jumper JP1 and JP2 are the power supply selectors of the
V850ES/Jx3-H - Plug it! board
.
JP2 JP1 Power Supply Source
1-2 short USB connector USB1
1-2 short
2-3 short USB connector USB2
2-3 short - AC adapter via connector CN4 or J1
