- Author
- Ken Händel
Create a new timer.
- Parameters
-
name | component name |
context | event context |
parent | the MOS6526 which this Timer belongs to |
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
-
void Timer::latchLo |
( |
uint8_t |
data | ) |
|
Set low byte of Timer start value (Latch).
- Parameters
-
void Timer::setControlRegister |
( |
uint8_t |
cr | ) |
|
Set CRA/CRB control register.
- Parameters
-
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!
int_least32_t Timer::state |
|
protected |
CRA/CRB control register / state.
