4.12

TIM4 - 8-bit basic timer



8-bit autoreload, adjustable prescaler ratio to any power of 2 from 1 to 128



Clock source: CPU clock



Interrupt source: 1 x overflow/update

4.13

Analog-to-digital converter (ADC1)

STM8S005C6/K6 value line products contain a 10-bit successive approximation A/D

converter (ADC1) with up to 10 multiplexed input channels and the following main features:



Input voltage range: 0 to VDDA



Conversion time: 14 clock cycles



Single and continuous, buffered continuous conversion modes



Buffer size (10 x 10 bits)



Scan mode for single and continuous conversion of a sequence of channels



Analog watchdog capability with programmable upper and lower thresholds



Analog watchdog interrupt



External trigger input



Trigger from TIM1 TRGO



End of conversion (EOC) interrupt

Note:

Additional AIN12 analog input is not selectable in ADC scan mode or with analog watchdog.

Values converted from AIN12 are stored only into the ADC_DRH/ADC_DRL registers.

4.14
