Pulse Width Modulator (PWM)

If latched faults are conﬁgured, the application must call ROM_PWMGenFaultClear() to clear

each trigger.

Note:

This function is only available on devices supporting extended PWM fault handling.

Returns:

Returns the current state of the fault triggers for the given PWM generator. A set bit indicates

that the associated trigger is active. For PWM_FAULT_GROUP_0, the returned value is

a logical OR of PWM_FAULT_FAULT0, PWM_FAULT_FAULT1, PWM_FAULT_FAULT2,

or PWM_FAULT_FAULT3. For PWM_FAULT_GROUP_1, the return value is the log-

ical 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.

15.2.1.11 ROM_PWMGenFaultTriggerGet

Returns the set of fault triggers currently conﬁgured for a given PWM generator.

Prototype:

uint32_t

ROM_PWMGenFaultTriggerGet(uint32_t ui32Base,

uint32_t ui32Gen,

uint32_t ui32Group)

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_PWMGenFaultTriggerGet is a function pointer located at ROM_PWMTABLE[26].

Parameters:

ui32Base is the base address of the PWM module.

ui32Gen is the PWM generator whose fault triggers are being queried. Must be one of

PWM_GEN_0, PWM_GEN_1, PWM_GEN_2, or PWM_GEN_3.

ui32Group indicates the subset of faults that are being queried. This must be

PWM_FAULT_GROUP_0 or PWM_FAULT_GROUP_1.

Description:

This function allows an application to query the current set of inputs that contribute towards the

generation of a fault condition to a given PWM generator.

Note:

This function is only available on devices supporting extended PWM fault handling.

Returns:

Returns the current fault triggers conﬁgured for the fault group provided. For

PWM_FAULT_GROUP_0, the returned value is a logical OR of PWM_FAULT_FAULT0,

PWM_FAULT_FAULT1, PWM_FAULT_FAULT2, or PWM_FAULT_FAULT3. For

PWM_FAULT_GROUP_1, the return value 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.
