4. For the EN pin of flash, switch charging, DC/DC and other chips, please select the PD's GPIO
control by default.
5. When ordinary GPIO is used as an input interrupt, edge wakeup is not supported when the system
sleeps, only level wakeup is supported.
3.13. I2C Interfaces
SC200L module provides four I2C interfaces. As an open-drain signal, the I2C interfaces need a pull-up
resistor on its external circuit, and the recommended power domain is 1.85V.
Table 15: Pin Definition of I2C Interfaces
3.14. SPI Interfaces
SC200L provides three SPI interfaces, which are multiplexed from UART and GPIO interfaces. These
interfaces can only support the master mode. SPI interfaces can be used for fingerprint recognition.
