Table 50. Start ADC Measurement SFR (ADCGO, 0xD8)

Bit

Address

Mnemonic

Default

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 is caused because the PLL lost lock.

6 to 3

0xDE to 0xDB

Reserved

Reserved.

0xDA

VDCIN_ADC_G

Set this bit to initiate an external voltage measurement. This bit is cleared when

the measurement request is received by the ADC.

0xD9

TEMP_ADC_GO

Set this bit to initiate a temperature measurement. This bit is cleared when the

measurement request is received by the ADC.

0xD8

BATT_ADC_GO

Set this bit to initiate a battery measurement. This bit is cleared when the

measurement request is received by the ADC.

Table 51. Battery Detection Threshold SFR (BATVTH, 0xFA)

Bit

Mnemonic

Default

Description

7 to 0

BATVTH

The battery ADC value is compared to this register, the battery threshold register. If BATADC is

lower than the threshold, an interrupt is generated.

Table 52. VDCIN ADC Value SFR (VDCINADC, 0xEF)

Bit

Mnemonic

Default

Description

7 to 0

VDCINADC

The VDCIN ADC value in this register is updated when an ADC interrupt occurs.

Table 53. Battery ADC Value SFR (BATADC, 0xDF)

Bit

Mnemonic

Default

Description

7 to 0

BATADC

The battery ADC value in this register is updated when an ADC interrupt occurs.

Table 54. Temperature ADC Value SFR (TEMPADC, 0xD7)

Bit

Mnemonic

Default

Description

7 to 0

TEMPADC

The temperature ADC value in this register is updated when an ADC interrupt occurs.
