UART, SPI, or I2C operation.
I2C is a two-wire bus that can be routed to multiple devices; each line of each bus need to supplement by a
2.2kΩ pull-up resistor

3.2.11 Power on Interface
Dedicated PMIC circuits continuously monitor events that might trigger a power-on sequence. If an event
occurs, these circuits power on the IC, determine the device’s available power sources, enable the correct
source. It is longer than 1s with pressing power-on key, for power on event. And it is suggested for 3s
powering on system. Power on/off key signal can be connected to ground through CON2402.6; the other
power on method is: when using CBL_PWR_N pin connect to ground, insert battery or power supply，SOM
