(when the Target MCU is an RL78/I1C with the Battery Backup
Function in Use)
The following describes points for caution regarding Figure 2-9 to Figure 2-14.
• Do not install capacitors, series resistors, or filters on signal lines; if attempted, correct communication may
not be established. There is an exception, however: capacitors can be inserted between VSS and
RESET_IN.
• The circuits and resistance values listed are recommended but not guaranteed. Determine the circuit design
and resistance values by taking into account the specifications of the target device and noise.
• Securely connect pins 2, 12, and 14 to GND of the user system. These pins are used for electrical
grounding as well as for monitoring of connection with the user system by the E1/E20/E2/E2 Lite. Securely
connect both pin 10 and pin 13.
