17.8.3 TIM2 Counter Modulo Registers
The read/write TIM2 modulo registers contain the modulo value for the counter. When the counter
reaches the modulo value, the overflow flag (TOF) becomes set, and the counter resumes counting from
$0000 at the next timer clock. Writing to the high byte (T2MODH) inhibits the TOF bit and overflow
interrupts until the low byte (T2MODL) is written. Reset sets the TIM2 counter modulo registers.
17.8.4 TIM2 Channel Status and Control Registers
Each of the TIM2 channel status and control registers does the following:

Flags input captures and output compares
Enables input capture and output compare interrupts
Selects input capture, output compare, or PWM operation
Selects high, low, or toggling output on output compare
Selects rising edge, falling edge, or any edge as the active input capture trigger
Selects output toggling on TIM2 overflow
Selects 0% and 100% PWM duty cycle
Selects buffered or unbuffered output compare/PWM operation
