Description

0xDF

PLLACK

Set this bit to clear the PLL fault bit, PLL_FLT in the PERIPH register. A PLL

fault is generated if a reset was caused because the PLL lost lock.

0xDB

Reserved

0xDA

VADC

Set this bit to initiate an externalvoltage measurement. This bit will be

cleared when the measurement request is received by the ADC.

0xD9

TADC

Set this bit to initiate a temperature measurement. This bit will be cleared

when the measurement request is received by the ADC.

0xD8

BTADC

Set this bit to initiate a battery measurement. This bit will be cleared when

the measurement request is received by the ADC.
