DETECT-IT RL78/I1D detector boards kit
5.2.1
Oscillators
Each board is equipped with 2 oscillators:
• A 20 MHz oscillator
The 20 MHz oscillator is sold onto each board and connected to the MCU. But it is not used by the application.
Instead the internal High Speed on-chip oscillator of the RL7/I1D is used by each application. So pin P121/X1
and pin P122/X2 are used as Input.
• Please change the settings if you wish to use the external oscillator.
• A 32,768kHz quartz
It is connected to the MCU
It is operating and used by the application (especially by the RTC).
