Control Register
| EN | Enable 0 (Disable): Timer is disabled and does not operate 1 (Enable): Timer is enabled and can operate |
| RST | Reset Timer 0 (Reserved): Write as ZERO if necessary 1 (Reset_Timer): Reset the Timer |
| CNT | Counting direction 0 (Count_UP): Timer Counts UO and wraps, if no STOP condition is set 1 (Count_DOWN): Timer Counts DOWN and wraps, if no STOP condition is set 2 (Toggle): Timer Counts up to MAX, then DOWN to ZERO, if no STOP condition is set |
| MODE | Operation Mode 0 (Continous): Timer runs continously 1 (Single_ZERO_MAX): Timer counts to 0x00 or 0xFFFFFFFF (depending on CNT) and stops 2 (Single_MATCH): Timer counts to the Value of MATCH Register and stops 3 (Reload_ZERO_MAX): Timer counts to 0x00 or 0xFFFFFFFF (depending on CNT), loads the RELOAD Value and continues 4 (Reload_MATCH): Timer counts to the Value of MATCH Register, loads the RELOAD Value and continues |
| PSC | Use Prescaler 0 (Disabled): Prescaler is not used 1 (Enabled): Prescaler is used as divider |
| CNTSRC | Timer / Counter Source Divider 0 (CAP_SRC): Capture Source is used directly 1 (CAP_SRC_div2): Capture Source is divided by 2 2 (CAP_SRC_div4): Capture Source is divided by 4 3 (CAP_SRC_div8): Capture Source is divided by 8 4 (CAP_SRC_div16): Capture Source is divided by 16 5 (CAP_SRC_div32): Capture Source is divided by 32 6 (CAP_SRC_div64): Capture Source is divided by 64 7 (CAP_SRC_div128): Capture Source is divided by 128 8 (CAP_SRC_div256): Capture Source is divided by 256 |
| CAPSRC | Timer / Counter Capture Source 0 (CClk): Core Clock 1 (GPIOA_0): GPIO A, PIN 0 2 (GPIOA_1): GPIO A, PIN 1 3 (GPIOA_2): GPIO A, PIN 2 4 (GPIOA_3): GPIO A, PIN 3 5 (GPIOA_4): GPIO A, PIN 4 6 (GPIOA_5): GPIO A, PIN 5 7 (GPIOA_6): GPIO A, PIN 6 8 (GPIOA_7): GPIO A, PIN 7 9 (GPIOB_0): GPIO B, PIN 0 10 (GPIOB_1): GPIO B, PIN 1 11 (GPIOB_2): GPIO B, PIN 2 12 (GPIOB_3): GPIO B, PIN 3 13 (GPIOC_0): GPIO C, PIN 0 14 (GPIOC_5): GPIO C, PIN 1 15 (GPIOC_6): GPIO C, PIN 2 |
| CAPEDGE | Capture Edge, select which Edge should result in a counter increment or decrement 0 (RISING): Only rising edges result in a counter increment or decrement 1 (FALLING): Only falling edges result in a counter increment or decrement 2 (BOTH): Rising and falling edges result in a counter increment or decrement |
| TRGEXT | Triggers an other Peripheral 0 (NONE): No Trigger is emitted 1 (DMA1): DMA Controller 1 is triggered, dependant on MODE 2 (DMA2): DMA Controller 2 is triggered, dependant on MODE 3 (UART): UART is triggered, dependant on MODE |
| RELOAD | Select RELOAD Register n to reload Timer on condition 0 (RELOAD0): Selects Reload Register number 0 1 (RELOAD1): Selects Reload Register number 1 2 (RELOAD2): Selects Reload Register number 2 3 (RELOAD3): Selects Reload Register number 3 |
| IDR | Selects, if Reload Register number is incremented, decremented or not modified 0 (KEEP): Reload Register number does not change automatically 1 (INCREMENT): Reload Register number is incremented on each match 2 (DECREMENT): Reload Register number is decremented on each match |
| S | Starts and Stops the Timer / Counter 0 (STOP): Timer / Counter is stopped 1 (START): Timer / Counter is started |
