TMS570LS0714: Using NHET Pin as an OUTPUT giving problems

Part Number: TMS570LS0714
Other Parts Discussed in Thread: HALCOGEN

Hi,

I'm working with the following HERCULES MCU: TMS570LS0714PGE. I'm trying to use the pin N2HET[14] as an output pin to send me a signal. The signal is generated through a HET program. However, every time I check the checkbox for output direction for pin 14, I can't seem to get it to work. Each time I alter a working application to configure the input/output configuration on the N2HET2[14] pin to OUTPUT, that seems to crash the MCU every time it tries to run the application. This also seems to be the case when I try for other pins within the same module. In the following bullet points, I leave the configurations I'm using for this procedure in HALCOGEN (each bullet point has a print attachment with the same number):

  1. PINMUX TAB Configuration: In line 33 I've selected the HET2_14 option and no conflicts arose;
  2. HET2 TAB - HET2 Global Timing Configuration: Nothing particular, normal clock configuration with both LRPs and HRPs prescales well defined;
  3. HET2 TAB - Pin 8-15: I've selected the Bit 14 direction (OPTION: DIR) to configure the pin as an output, and I've also selected the pulldown configuration (OPTION: PSL). I've copied what's implemented for other pins used as outputs and these work fine. However for pin NHET2[14] whenever I enable the DIR option problems starts.

Given this information, I would like to ask you if you have any insights of what I could be doing wrong? I've also tried messing with the pin configurations of pin N2HET1[07] which is a shared pin with N2HET2[14] through a MUX. Also tried to match the configuration between the two, but somehow I can't get it to work.

Thank you very much for your attention.

Best regards, 

Martin Blocher
