C28x-ePWM

Assign ePWM signals to GPIO pins. You can set the following parameters for ePWM:

EPWM clock divider (EPWMCLKDIV)

Select the ePWM clock divider. This parameter is available only for F2807x, F2837x, F2838x processors.

Select the 'EPWM clock divider (EPWMCLKDIV)' option used for CPU1

Available only for CPU2 of dual C28x core processors. Its value must be the same as the value of the parameter EPWM clock divider (EPWMCLKDIV) selected in CPU1.

TZx pin assignment

Assign the trip-zone input x (TZx) to a GPIO pin.

For F2807x, F2837x and F2838x processors, select None or GPIO#.

Note

To enter the GPIO numbers in theTZ# pin assignment parameters for F2807x, F2837x and F2838x processors, select CPU1 in Build options >Select CPU.

Note

The TZ# pin assignments are available only for TI F280x processors.

SYNCI pin assignment

Assign the ePWM external sync pulse input (SYNCI) to a GPIO pin.

For F2807x, F2837x and F2838x processors, select None or GPIO#.

Note

To enter the GPIO numbers in SYNCI pin assignment for F2807x, F2837x and F2838x processors, you must select CPU1 in Build options >Select CPU.

SYNCO pin assignment

Assign the ePWM external sync pulse output (SYNCO) to a GPIO pin.

Note

SYNCI and SYNCO pin assignments are available for TI F28044, TI F280x, TI Delfino F2833x, TI Delfino F2834x, TI Piccolo F2802x, TI Piccolo F2803x, TI Piccolo F2806 processors.

PWM#x pin assignment

Assign the GPIO pin to the PWM#x module.

GPTRIP#SEL pin assignment(GPIO0~63)

Assign the ePWM trip-zone input to a GPIO pin.

Note

The GPTRIP#SEL pin assignment is available only for TI Concerto F28M35x/F28M36x processors.

PWM1SYNCI/ GPTRIP6SEL pin assignment

Assign the ePWM sync pulse input (SYNCI) to a GPIO pin.

Note

The PWM1SYNCI/GPTRIP#SEL pin assignments are available only for TI Concerto F28M35x/F28M36x processors.

DCxHTRIPSEL (Enter Hex value between 0 and 0x6FFF) / DCBHTRIPSEL (Enter Hex value between 0 and 0x6FFF)

Assign the Digital Compare A high trip input to a GPIO pin.

Note

DCxHTRIPSel pin assignment is available only for TI Concerto F28M35x/F28M36x processors.

DCxLTRIPSEL (Enter Hex value between 0 and 0x6FFF) / DCBLTRIPSEL (Enter Hex value between 0 and 0x6FFF)

Assign the Digital Compare A low trip input to a GPIO pin.

Note

The DCxLTRIPSEL pin assignment is available only for TI Concerto F28M35x/F28M36x processors.
