- Hardware organization
Compare register with double buffer
Input capture register
Timer interrupt
- Timer functions
Square wave output ( Timer pulse output ), Event count,
High precision PWM output ( Cycle/Duty variable continuously ),
Timer synchronous output, Input capture function ( Both edges
can be operated )
- Real time output control
PWM output is controlled in real time by the external interrupt 0 (IRQ0).
At the interrupt enable edge of the external interrupt 0 (IRQ0), PWM output
( Timer output ) is controlled in 3 values ; "fixed high", "fixed low",
"Hi-z".
