Bit 23 TSVREFE: Temperature sensor and V
REFINT
enable
This bit is set and cleared by software to enable/disable the temperature sensor and the
V
REFINT
channel.
0: Temperature sensor and V
REFINT
channel disabled
1: Temperature sensor and V
REFINT
channel enabled
Note: VBATE must be disabled when TSVREFE is set. If both bits are set, only the VBAT
conversion is performed.
Bit 22 VBATE: V
BAT
enable
This bit is set and cleared by software to enable/disable the V
BAT
channel.
0: V
BAT
channel disabled
1: V
BAT
channel enabled
Bits 21:18 Reserved, must be kept at reset value.
Bits 17:16 ADCPRE: ADC prescaler
Set and cleared by software to select the frequency of the clock to the ADC. The clock is
common for all the ADCs.
Note: 00: PCLK2 divided by 2
01: PCLK2 divided by 4
10: PCLK2 divided by 6
11: PCLK2 divided by 8
Bits 15:0 Reserved, must be kept at reset value.
