QuickStart Guide YRPBRL78G14 RENESAS 1 Installation The installation of the demonstration files and GUI will be automatically performed by the DVD installer If the DVD does not autostart please run the Setup executable file on the DVD and follow the directions for the installation Please note that the user will require administration rights to the host PC in order to install the demonstration and tool software 2 Connection 1 First ensure that a jumper is fitted on CN4 and that the YRPBRL78G14 stick jumpers are configured as shown below Jumpers Configuration CN8 2 3 CN7 2 3 CN6 2 3 CN11 2 3 D2 D1 LED E1 Connector CN8 aoe Unfitted CN7 SW1 USB Connector CN10 CN6 CN2 CN4 SW2 Switches o a a d a HHHH UHNHHUH S CN5 CN3 IC1 RL78G14 R5 Potentiometer Very Low Power Seiko 32KHz Resonator 2 Next connect the YRPBRL78G14 USB stick to the host PC using the USB cable provided and when the USB stick is connected diode D1 should be on indicating that power is supplied to the YRPBRL78G14 Stick 3 _ If this is the first time the USB stick is connected to the host PC the drivers will be installed automatically Accept any permission dialogs that arise On completion the driver should be Renesas Starter Kit Virtual UART This can be verified by in the Device Manager and note the com port assigned to the USB stick YRPBRL78G14 Quick Start Guide 1 D010744_11 3 S
4. ement of the RL78 G14 device Remove this jumper and connect a multi meter to these pins as shown below Caution Connect and turn on the ammeter prior to starting the demonstration Make sure there is no short between the terminals Make sure the multi meter is set to measure current Set the appropriate range Caution Current measurements can be from uA to mA Some multi meters disconnect when the range is changed This will interrupt the voltage supply to the MCU resulting in a MCU reset It is recommended that the GUI is disconnected from the stick and power is then removed from the stick The appropriate range can then be selected on the multi meter before re connecting the YRPBRL78G14 stick to the host PC and re starting the GUI Each power mode enables and disables different MCU peripherals The fewer peripherals enabled the lower the MCU s current consumption will be Power Mode CPU 32 MHz 32 KHz UART Timer ADC RTC LVD Flash RAM RUN On On On On On On On Off Off On HALT Off On On On On On On Off Off On STOP Off Off On Off Off Off On Off Off On SNOOZE Off Off On Off Off On On Off Off On periodically YRPBRL78G14 Quick Start Guide 3 DO10744_11 Self Test tab The Self Test tab includes the new self test features included on the RL78 G14 device and the Event Link Controller ELC feature These include e Measurement of the system clock frequency i e for IEC 60730 60335 e Test of the user switches e _ Test of the ELC
