Hi,
I have a development board with pin L24 (TIMI0) of the C6678 DSP pulled to GND via a 4K7 ohm resistor. When I look in the DEVSTAT register i can see that bit 16 is 0 as expected. However, when I remove this resistor and power up my board again, the DEVSTAT register now has bit 16 set to 1. I do not have a signal driving the TIMI0 pin on my design.
Is this pin supposed to be internally pulled down? I am planning a redesign and had hoped to change this resistor to pull up, allowing the IPD resistor to set the PCIESSEN bit to 0 but this does not seem to happen. I know the EVM board also ties this pin to GND, so is it a mistake in the datasheet? Or is it just the the IPD/U resistors of the DSP should not be relied upon as you say in the datasheet?
Rgds,
