Hi,
I set 4 outputs PWM waveform (EPWM0A, EPWM0B, EPWM1A, EPWM1B) through PINMUX's registers, and all waveforms seem to be working ok except EPWM0A output. In the scope it shows a clock of 25 Mhz.
from the datasheet I know that SPI0_CLK/EPWM0A/GP1[8]/MII_RXCLK Control are multiplexed in PINMUX3_3_0 and by selecting 2h the option would be
EPWM0A. I can see through the debugger using XDS200 that EPWM0A is selected in the pinmux register but in the scope the output is very noisy and it looks like
a clock.
would that be SPI clock or MII_RXCLCK even though are not selected and how can I eliminate that by totally disabling these clock signals
Thanks for the support
