Hi,
I am trying to use TMS320F28035 in my application. I have a question about this device.
What is the maximum toggle rate on a GPIO port? Datasheet suggests 15MHz but I only get ~4.27MHz when I do
e.g:
GpioDataRegs.GPBCLEAR.bit.GPIO43 = 1;
GpioDataRegs.GPBSET.bit.GPIO43 = 1;
GpioDataRegs.GPBCLEAR.bit.GPIO43 = 1;
GpioDataRegs.GPBSET.bit.GPIO43 = 1;
I am running 60MHz CPU clock. I have verified that by monitoring XCLKOUT pin (GPIO18).
I have tried checking the GPIO pin toggle using TOGGLE (instead of SET and CLEAR) as well but
the result is same.
Can someone please help me out with this?
regards,
Pramod
