Function Documentation

void ppciPtimInit (  void   )

Timer initialization routine This init routine is called by ppciInit (from sysHwInit) during system boot. No initialization is currently performed -- this routine merely servers as a stub to force inclusion by the linker.

STATUS ptimCnf (  int  ptimNum, int  cntDir, int  clkSrc, int  clkFreq, int  reloadTmr, int  sigInt, int  sigMode, int  snap, int  extClear )

Configure a programmable timer. Configure a programmable timer This routine configures a programmable timer. Any input or output PIDs used by the timer must be configured separately via pidCnf(). Parameters: ptimNum  - Programmable timer number (1-3). cntDir  - Count direction: PTIM_CNT_DOWN or PTIM_CNT_UP clkSrc  - Clock source: PTIM_OSC_CLK or PTIM_PID_CLK clkFreq  - Clock frequency: PTIM_DIV4 or PTIM_DIV8 reloadTmr  - Terminal event: PTIM_STOP_TMR or PTIM_RELOAD_TMR sigInt  - Terminal signal: PTIM_SIG_MISC or PTIM_SIG_VEC sigMode  - Pulse/toggle signal: PTIM_PULSE_PID or PTIM_TOGL_PID snap  - Snapshot: PTIM_DIS_SNAP or PTIM_ENA_SNAP extClear  - External clear: PTIM_DIS_CLEAR or PTIM_ENA_CLEAR Returns: OK or ERROR.

STATUS ptimDisable (  int  ptimNum  )

Disable timer. Disable timer This routine disables a programmable timer, stops it from counting. Parameters: ptimNum  - Programmable timer number (1-3). Returns: OK or ERROR

STATUS ptimEnable (  int  ptimNum  )

Enable timer. Enable timer This routine enables a programmable timer, starts it counting. Parameters: ptimNum  - Programmable timer number (1-3). Returns: OK or ERROR.

STATUS ptimGet (  int  ptimNum, unsigned int *  pVal )

Get value of timer. Get value of timer This routine returns the current value of a programmable timer. Parameters: ptimNum  - Programmable timer number (1-3). pVal  - Pointer to return timer value. Returns: OK or ERROR

STATUS ptimGetReload (  int  ptimNum, unsigned int *  pVal )

Get reload value of timer. Get reload value of timer This routine returns the reload value of a programmable timer. Parameters: ptimNum  - Programmable timer number (1-3). pVal  - Pointer to return reload value. Returns: OK or ERROR.

STATUS ptimIntConnect (  int  ptimNum, VOIDFUNCPTR  isr, int  parm )

Connect ISR to PowerPCI programmable timer interrupt. Connect ISR to PowerPCI programmable timer interrupt This routine connects an interrupt service routine (ISR) to PowerPCI bridge programmable timer interrupt. Timer interrupts are enabled separate from this routine (by ptimIntEnable). The interrupt level being connected should not be enabled when this routine is called. The specified ISR will get control with interrupts disabled. Parameters: ptimNum  - Programmable timer number (1-3). isr  - Pointer to the ISR. parm  - A user-defined parameter to pass to the ISR when the interrupt occurs. Returns: OK or ERROR

STATUS ptimIntDisable (  int  ptimNum  )

Disable a PowerPCI programmable timer interrupt. Disable a PowerPCI programmable timer interrupt This routine disables the specified programmable timer interrupt of the PowerPCI bridge. Parameters: ptimNum  - Programmable timer number (1-3). Return values: OK  or ERROR

STATUS ptimIntEnable (  int  ptimNum  )

Enable a PowerPCI programmable timer interrupt This routine enables the specified programmable timer interrupt of the PowerPCI bridge. Parameters: ptimNum  - Programmable timer number (1-3). Returns: OK or ERROR

STATUS ptimSet (  int  ptimNum, unsigned int  value )

Set value of timer. Set value of timer This routine sets a programmable timer. Parameters: ptimNum  - Programmable timer number (1-3). value  - Value to load into timer. Returns: OK or ERROR

STATUS ptimSetReload (  int  ptimNum, unsigned int  value )

Set reload value of timer. Set reload value of timer This routine sets the reload value of a programmable timer. Parameters: ptimNum  - Programmable timer number (1-3). value  - Reload value. Returns: OK or ERROR.

unsigned int watchdogGet (  void   )

Read the value of the watchdog timer. Read the value of the watchdog timer Returns: The watchdog time couter value.

STATUS watchdogSet (  unsigned int  value  )

Set the value of the watchdog timer. Set the value of the watchdog timer Parameters: value  - The value to write to the watchdog timer. Returns: OK or ERROR
