Pulse Width Modulator (PWM)
15.2.1.12 ROM_PWMGenFaultTriggerSet
Configures the set of fault triggers for a given PWM generator.
Prototype:
void
ROM_PWMGenFaultTriggerSet(uint32_t ui32Base,
uint32_t ui32Gen,
uint32_t ui32Group,
uint32_t ui32FaultTriggers)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_PWMTABLE is an array of pointers located at ROM_APITABLE[8].
ROM_PWMGenFaultTriggerSet is a function pointer located at ROM_PWMTABLE[25].
Parameters:
ui32Base is the base address of the PWM module.
ui32Gen is the PWM generator whose fault triggers are being set. Must be one of
PWM_GEN_0, PWM_GEN_1, PWM_GEN_2, or PWM_GEN_3.
ui32Group indicates the subset of possible faults that are to be configured. This must be
PWM_FAULT_GROUP_0 or PWM_FAULT_GROUP_1.
ui32FaultTriggers defines the set of inputs that are to contribute towards generation of the
fault signal to the given PWM generator. For PWM_FAULT_GROUP_0, this is the log-
ical OR of PWM_FAULT_FAULT0, PWM_FAULT_FAULT1, PWM_FAULT_FAULT2,
or PWM_FAULT_FAULT3. For PWM_FAULT_GROUP_1, this is the logical
OR of PWM_FAULT_DCMP0, PWM_FAULT_DCMP1, PWM_FAULT_DCMP2,
PWM_FAULT_DCMP3, PWM_FAULT_DCMP4, PWM_FAULT_DCMP5,
PWM_FAULT_DCMP6, or PWM_FAULT_DCMP7.
Description:
This function allows selection of the set of fault inputs that is combined to gener-
ate a fault condition to a given PWM generator. By default, all generators use only
FAULT0 (for backwards compatibility) but if ROM_PWMGenConfigure() is called with flag
PWM_GEN_MODE_FAULT_SRC in the ui32Config parameter, extended fault handling is en-
abled and this function must be called to configure the fault triggers.
The fault signal to the PWM generator is generated by ORing together each of the sig-
nals whose inputs are specified in the ui32FaultTriggers parameter after having adjusted
the sense of each FAULTn input based on the configuration previously set using a call to
ROM_PWMGenFaultConfigure().
Note:
This function is only available on devices supporting extended PWM fault handling.
Returns:
None.
15.2.1.13 ROM_PWMGenIntClear
