Synopsis
Unsigned Integer *Add_Timer ( IN Unsigned integer nDuration)
Parameters
nDuration: Input parameter
Specifies duration of time in 10 ms units.
Return Value
Pointer to added timer. If the value is zero (NULL), there are no timers available.
This function can be called inside an ISR. When the timer expires (*pTimer == 0), it will be automatically
removed. If all timers are in use, a NULL pointer will be returned. The Process_Timers() routine must be
called to keep the timer updated.
Add_Timer_Func()
Purpose
Add a 10 ms software timer and the function to execute on timer expiration.
Synopsis
Unsigned Integer *Add_Timer_Func (
IN unsigned int nDuration,
IN void (*pfExpire (void)) );
Parameters
nDuration: Input parameter
Specifies duration of time in 10 ms units.
pfExpire: Input parameter
Specifies a pointer to the function to execute when the timer expires.
Return Value
Pointer to the added timer. If value is zero, there are no timers available.
Remove_Timer()
Purpose
Stop and remove the selected timer.
Synopsis
Void Remove_Timer ( IN unsigned integer *pTimerId );
Parameters
ptimerID: Input parameter
Specifies which timer to stop and remove. This is the value returned by the
Return Codes
None.
Process_Timers()
Purpose
Process and update the active timers. This function must be called from a
foreground routine whenever there is active timer.
Synopsis
Void Process_Timers ( void );
Parameters
None.
Return Codes
None.
4.2.13 User IO API – Available with all 73S12xxF Devices
The USER IO Pins can be configured, individually, as an interrupt source to Timer 0, Timer 1, INT0 or
INT1. For INT0 or INT1, the interrupt can be configured to occur on the rising edge/high level or falling
edge/low level. Only INT0 can be used to wake up the CPU from sleep/halt mode. This API includes:
