Pulse Width Modulator (PWM)
Prototype:
void
ROM_PWMOutputFaultLevel(uint32_t ui32Base,
uint32_t ui32PWMOutBits,
bool bDriveHigh)
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_PWMOutputFaultLevel is a function pointer located at ROM_PWMTABLE[22].
Parameters:
ui32Base is the base address of the PWM module.
ui32PWMOutBits are the PWM outputs to be modified. Must be the logical OR of
any of PWM_OUT_0_BIT, PWM_OUT_1_BIT, PWM_OUT_2_BIT, PWM_OUT_3_BIT,
PWM_OUT_4_BIT, PWM_OUT_5_BIT, PWM_OUT_6_BIT, or PWM_OUT_7_BIT.
bDriveHigh determines if the signal is driven high or low during an active fault condition.
Description:
This function determines whether a PWM output pin that is suppressed in response to a
fault condition is driven high or low. The affected outputs are selected using the parameter
ui32PWMOutBits. The parameter bDriveHigh determines the output level for the pins identi-
fied by ui32PWMOutBits. If bDriveHigh is true then the selected outputs are driven high when
a fault is detected. If it is false, the pins are driven low.
In a fault condition, pins which have not been configured to be suppressed via a call to
ROM_PWMOutputFault() are unaffected by this function.
Note:
This function is available only on devices which support extended PWM fault handling.
Returns:
None.

ROM_PWMTABLE is an array of pointers located at ROM_APITABLE[8].
ROM_PWMOutputInvert is a function pointer located at ROM_PWMTABLE[12].
Parameters:
ui32Base is the base address of the PWM module.
