bool Timer::getPb | ( | uint8_t | reg | ) | const [inline] |
Get PB6/PB7 Flipflop state.
reg | value of the control register |
int_least32_t Timer::getState | ( | ) | const [inline] |
Get current state value.
uint_least16_t Timer::getTimer | ( | ) | const [inline] |
Get current timer value.
void Timer::latchHi | ( | uint8_t | data | ) |
void Timer::latchLo | ( | uint8_t | data | ) |
void Timer::reset | ( | ) |
Reset timer.
void Timer::setControlRegister | ( | uint8_t | cr | ) |
Set CRA/CRB control register.
cr | control register value |
void Timer::setPbToggle | ( | bool | state | ) | [inline] |
Set PB6/PB7 Flipflop state.
state | PB6/PB7 flipflop state |
void Timer::syncWithCpu | ( | ) |
Perform cycle skipping manually.
Clocks the CIA up to the state it should be in, and stops all events.
void Timer::wakeUpAfterSyncWithCpu | ( | ) |
Counterpart of syncWithCpu(), starts the event ticking if it is needed. No clock() call or anything such is permissible here!
MOS6526* const Timer::parent [protected] |
int_least32_t Timer::state [protected] |
CRA/CRB control register / state.
