Member Enumeration Documentation

ClockSource

enum Timer::Config::ClockSource

Clock sources.

Enumerator
NO_CLOCK	No clock source (timer stopped).
DIV_1	I/O clock without prescaling.
DIV_8	I/O clock, prescaler set to 1/8.
DIV_64	I/O clock, prescaler set to 1/64.
DIV_256	I/O clock, prescaler set to 1/256.
DIV_1024	I/O clock, prescaler set to 1/1024.
EXT_FALLING_EDGE	External clock source, clock on falling edge.
EXT_RISING_EDGE	External clock source, clock on rising edge.

CompareOutputMode

enum Timer::Config::CompareOutputMode

Compare output modes.

Note

Not all modes are available for each operation mode:

Compare output mode	Normal	Phase correct PWM	CTC mode	Fast PWM
DISCONNECTED	Yes	Yes	Yes	Yes
NON_PWM_TOGGLE_ON_COMPARE_MATCH	Yes	No	Yes	No
NON_PWM_CLEAR_ON_COMPARE_MATCH	Yes	No	Yes	No
NON_PWM_SET_ON_COMPARE_MATCH	Yes	No	Yes	No
PHASE_CORRECT_PWM_CLEAR_WHEN_ABOVE	No	Yes	No	No
PHASE_CORRECT_PWM_SET_WHEN_ABOVE	No	Yes	No	No
FAST_PWM_NON_INVERTING	No	No	No	Yes
FAST_PWM_INVERTING	No	No	No	Yes

Enumerator
DISCONNECTED	Normal port operation, OC pin disconnected.
NON_PWM_TOGGLE_ON_COMPARE_MATCH	Toggle OC pin on compare match.
NON_PWM_CLEAR_ON_COMPARE_MATCH	Clear OC pin on compare match.
NON_PWM_SET_ON_COMPARE_MATCH	Set OC pin on compare match.
PHASE_CORRECT_PWM_CLEAR_WHEN_ABOVE	Clear OC pin on compare match when up-counting. Set OC pin on compare match when down-counting.
PHASE_CORRECT_PWM_SET_WHEN_ABOVE	Set OC pin on compare match when up-counting. Clear OC pin on compare match when down-counting.
FAST_PWM_NON_INVERTING	Clear OC pin on compare match, set OC pin at BOTTOM.
FAST_PWM_INVERTING	Set OC pin on compare match, clear OC pin at BOTTOM.

OperationMode

enum Timer::Config::OperationMode

Operation modes.

Enumerator
NORMAL_MODE	Normal mode (free running timer).
PHASE_CORRECT_PWM_MODE	Phase correct PWM.
CTC_MODE	Clear Timer on Compare match.
FAST_PWM_MODE	Fast PWM mode.
