Figure 25: Reference Circuit Design for LCM1 Interface
MIPI are high speed signal lines. It is recommended that common-mode filters should be added in series
near the LCM connector, so as to improve protection against electromagnetic radiation interference.
ICMEF112P900MFR using ICT is recommended.
It is recommended to read the LCM ID register through MIPI when compatible design with other displays
is required. If several LCM models share the same IC, it is recommended that LCM module factory burn
the OTP register to distinguish different screens. Customers can also select the LCD_ID pin of LCM to
connect the ADC pin of the SC66 module, but it should be noted that the output voltage of LCD_ID should
not exceed the voltage range of the ADC pin.
