Analog-to-digital converters (ADC) RM0351
596/1830 DocID024597 Rev 5
18.6.10 ADC watchdog threshold register 3 (ADC_TR3)
Address offset: 0x28
Reset value: 0x00FF 0000
Bits 31:24 Reserved, must be kept at reset value.
Bits 23:16 HT2[7:0]: Analog watchdog 2 higher threshold
These bits are written by software to define the higher threshold for the analog watchdog 2.
Refer to Section 18.4.29: Analog window watchdog (AWD1EN, JAWD1EN, AWD1SGL, AWD1CH,
AWD2CH, AWD3CH, AWD_HTx, AWD_LTx, AWDx)
Note: Software is allowed to write these bits only when ADSTART=0 and JADSTART=0 (which
ensures that no conversion is ongoing).
Bits 15:8 Reserved, must be kept at reset value.
Bits 7:0 LT2[7:0]: Analog watchdog 2 lower threshold
These bits are written by software to define the lower threshold for the analog watchdog 2.
Refer to Section 18.4.29: Analog window watchdog (AWD1EN, JAWD1EN, AWD1SGL, AWD1CH,
AWD2CH, AWD3CH, AWD_HTx, AWD_LTx, AWDx)
Note: Software is allowed to write these bits only when ADSTART=0 and JADSTART=0 (which
ensures that no conversion is ongoing).

Bits 23:16 HT3[7:0]: Analog watchdog 3 higher threshold
These bits are written by software to define the higher threshold for the analog watchdog 3.
Refer to Section 18.4.29: Analog window watchdog (AWD1EN, JAWD1EN, AWD1SGL, AWD1CH,
AWD2CH, AWD3CH, AWD_HTx, AWD_LTx, AWDx)
Note: Software is allowed to write these bits only when ADSTART=0 and JADSTART=0 (which
ensures that no conversion is ongoing).
Bits 15:8 Reserved, must be kept at reset value.
Bits 7:0 LT3[7:0]: Analog watchdog 3 lower threshold
These bits are written by software to define the lower threshold for the analog watchdog 3.
This watchdog compares the 8-bit of LT3 with the 8 MSB of the converted data.
Note: Software is allowed to write these bits only when ADSTART=0 and JADSTART=0 (which
ensures that no conversion is ongoing).
