OPT3101: Question about OPT3101 design

Part Number: OPT3101

Hi team

Happy new year. 

I design the custom board with OPT3101. 

I use the EFM32Gxx. 

Our application is to measure the distance of crane lifter.

I set the opt3101 as Continuous mode.

My question is bellow.

1. RST_MS pin must connect to GPIO of MCU? (Default High)

   - This pin has used the trigger of mono shot mode.(As external trigger) 

     It is possible to use the internal trigger, MONOSHOT_BIT of the register?

      Is it same performance?
