VREF jumper pin can switch the supply source of VREF pin of MCU.
VREF
Contents
VDD
VREF pin is connected to 2pin of PWR jumper pin.
USR
VREF pin is connected to 19pin (UVREF) of CN2.
VREF jumper pin set to “VDD” if power supply from VDD as same as selecting PWR jumper pin.
VREF jumper pin set to “USR” if power supply from CN2 connector.
・
SPVDD jumper pin(J3)
SPVDD jumper pin can switch the supply source of SPVDD pin of MCU.
SPVDD
Contents
VDD
SPVDD pin is connected to 2pin of PWR jumper pin.
USR
SPVDD pin is connected to 3/4pins (USPVDD) of CN2.
SPVDD jumper pin set to “VDD” if power supply from VDD as same as selecting PWR jumper pin.
SPVDD jumper pin set to “USR” if power supply from CN1 connector.
5.2. LED(P22-P24)
P22-24 pins of MCU on the RB-D610Q327TB48 allow direct LEDs drive. Enable to use LEDs connecting these pins when
the N-channel open drain output is selected. Unmount register on the board indicated by “R4-R6” when not using LEDs.
Figure 3 shows the LED circuit processing example.
