Constructor & Destructor Documentation

Timer::Timer ( const char *  name,
EventContext context,
MOS6526 parent 
) [inline, protected]

Create a new timer.

Parameters:
name component name
context event context
parent the MOS6526 which this Timer belongs to


Member Function Documentation

bool Timer::getPb ( uint8_t  reg  )  const [inline]

Get PB6/PB7 Flipflop state.

Parameters:
reg value of the control register
Returns:
PB6/PB7 flipflop state

int_least32_t Timer::getState (  )  const [inline]

Get current state value.

Returns:
current state value

uint_least16_t Timer::getTimer (  )  const [inline]

Get current timer value.

Returns:
current timer value

void Timer::latchHi ( uint8_t  data  ) 

Set high byte of Timer start value (Latch).

Parameters:
data high byte of latch

void Timer::latchLo ( uint8_t  data  ) 

Set low byte of Timer start value (Latch).

Parameters:
data low byte of latch

void Timer::reset (  ) 

Reset timer.

void Timer::setControlRegister ( uint8_t  cr  ) 

Set CRA/CRB control register.

Parameters:
cr control register value

void Timer::setPbToggle ( bool  state  )  [inline]

Set PB6/PB7 Flipflop state.

Parameters:
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!


Member Data Documentation

MOS6526* const Timer::parent [protected]
