TDC1000-C2000EVM: TDC1000-C2000EVM: TCD stop & start monitor

Part Number: TDC1000-C2000EVM

Hi Sir

I find the SV601136B shows that stop & start signal are monitored by the same GPIO11 and use 2 diodes and 2 resistances.

Cause we need to control the size of PCB and cost reduction; we would like to delete the components and use 2 different GPIO to monitor stop & start.

Is there any comments or suggestions? SV601136B design purpose? 

Thank you for your help.
