[HRPWM] Frequency Considerations
Welcome to the C2000™ Microcontrollers Section of the TI E2E Support Community. Ask questions, share knowledge, explore ideas, and help solve problems with fellow engineers. To post a question, click on the forum tab then "New Post".
Can a PWM signal of 50% duty cycle of either 13.5MHz or 27MHz be generated on the 28335?
Please refer to the data manual.
Per the data manual, the maximum toggling
frequency of the I/Os (this would include the PWM pins) is 25MHz. See section
6.9.1 GPIO - Output Timing. The PWM module itself should be capable of handling
what you ask, but it is a limitation of the output buffers. It is not that they
would stop switching above this limit but that the signal integrity would
