3.11.3 HKADC(House Keeping ADC)
The MSM6245 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 MSM6245 device has six analog input pins which are multiplexed to the input of the
internal HKADC.
