Timer source is the system clock divided by the prescaler.
System clock divider = 4.
System clock divider = 16.
System clock divider = 64.
Description
The timer continues to operate during debug break points.
The timer stops operation and holds count value during debug
break points.
Timer source is the Real Time Clock Input.
Timer source is the Event Count (ECx) input—falling edge.
For Timer 1 this is EC0.
For Timer 2, this is EC1.
Timer source is the Event Count (ECx) input—rising edge.
For Timer 1 this is EC0.
For Timer 2, this is EC1.
System clock divider = 256.
The timer operates in SINGLE PASS mode. TIM_EN (bit 0) is
reset to 0 and counting stops when the end-of-count value is
reached.
The timer operates in CONTINUOUS mode. The timer reload
value is written to the counter when the end-of-count value is
reached.
