• Methods not supported for Freescale HC(S)08, RS08, HCS12(X), and CFV1 derivatives except CFV1 AG family.
  • Enable - Enables the component - starts the watchdog timer counting.
    
    ANSIC prototype: byte Enable(void)
    
    • Return value:byte - Error code, possible codes:
      ERR_OK - OK
      ERR_SPEED - This device does not work in the active speed mode
      ERR_PROTECT - This device does is protected
    
    
  • Disable - Disables the component - stops the watchdog timer counting.
    
    ANSIC prototype: byte Disable(void)
    
    • Return value:byte - Error code, possible codes:
      ERR_OK - OK
      ERR_SPEED - This device does not work in the active speed mode
      ERR_PROTECT - This device does is protected
    
    
• Clear - Clears the watchdog timer (it makes the timer restart from zero).
  
  ANSIC prototype: byte Clear(void)
  
  • Return value:byte - Error code, possible codes:
    ERR_OK - OK
    ERR_SPEED - This device does not work in the active speed mode
    ERR_DISABLED - The Component is disabled
  
  
• Methods for Freescale 56800/E derivatives and CFV1 AG family.
  • Protect - Protects the watchdog against changing its state or period (against disabling the watchdog if it is enabled and vice versa). This protection can be de-activated only by resetting the CPU.
    
    ANSIC prototype: byte Protect(void)
    
    • Return value:byte - Error code, possible codes:
      ERR_OK - OK
      ERR_SPEED - This device does not work in the active speed mode
      ERR_PROTECT - This device does is protected
    
    

Note: Some methods can be implemented as macros.
