3.10.3 HKADC(House Keeping ADC)

The MSM6280 device has an on-chip 8-bit analog-to-digital converter (HKADC) which is tended to

digitize DC signals corresponding to analog parameters such as battery voltage, temperature, and RF

power levels. The MSM6280 device has six analog input pins which are multiplexed to the input of the

internal HKADC.
