TIMERS The circuit contains 4 independent 8-bit timers configurable as 2 16-bit timers. • Each of it can be individually configured with: • 6 internal clock sources and 2 external clock sources from PA, PC terminals • Individual Start/Stop selection by SW or from various IO terminals • Timer interrupt selection • Auto-reload(free-running) and Auto-Stop mode • Input Capture on hardware events (terminal input) or SW driven • Output Compare for signal generation • PWM and Frequency output • RTZ, RTO output clock capabilities • Timer outputs mapping on various IO terminals • Always also provides complementary level output to increase overall voltage swing. The timers are implemented as up-counters, counting from 0x00 to RegTimXFull or as a free running counter cycling from 0x00 to RegTimXFull. If the full value changes while the timer is running, the previous full value will be used for the full event detection. The new full value will be used for the next counting cycle. The timer status value (actual count value) is readable in registers RegTimXStatus. 17.1 TIMER CHAINING Possible configurations are: • Timer1, Timer2, Timer3, Timer4 used independently • Timer1 and Timer2 chained together (Timer12); Timer3 and Timer 4 used independently • Timer1 and Timer2 used independently; Timer3 and Timer4 chained (=Timer34) • Timer1 and Timer2 chained together (Timer12); Timer3 and Timer4 chained (=Timer34) Timer1 and Timer2 are chained and able to work as 16-bits timer when Tim12Chain in RegTimersCfg is high. In this case, the configuration is set by the Timer1 and Timer2 (slave) is the MSB. Timer3 and Timer4 are chained and able to work as 16-bits timer when Tim34Chain in RegTimersCfg is high. In this case, the configuration is set by the Timer3 and Timer4 (slave) is the MSB. Figure 15, Timer chaining |
