PMIC (Power Management IC)

getSystemStatus()

byte getSystemStatus();

Returns the raw value of the read-only system status register (REG08). This register reports the power source (VBUS), charging state, DPM/thermal regulation status, and power-good status all at once. The individual bits can be decoded with the following methods, described in more detail in the System status register section, below:

• getVbusStat() — bits 7:6, power source (unknown, USB host, adapter, OTG)
• getChargingStat() — bits 5:4, charging state
• getDPMStat() — bit 3, in dynamic power management (VINDPM or IINDPM)
• isPowerGood() — bit 2, power good
• isHot() — bit 1, in thermal regulation
• getVsysStat() — bit 0, in minimum system voltage regulation
