Note:
1. If using I2C interface mode, the resistance of SDA signal should be lower than 300Ω (if the system pull up resistor is
4.7KΩ).
If using 3-Line or 4-Line SPI interface with VDD1 less than 2.4V, the SDA signal resistance should be less than 500Ω.
2. To prevent the ESD pulse resetting the internal register, applications should increase the resistance of RESB signal
(add a series resistor or increase ITO resistance). The value is different from modules.
3. This table defines the actual ITO resistance. The actual ITO resistance should in these ranges, not the calculated ITO
resistance value. The ITO tolerance should be considered.
4. The option setting to be “H” should connect to VDD1.
5. The option setting to be “L” should connect to VSS1.
