Description:
Reading returns the list possible master modes which are:
- "reset" : The UG bit from the TIMx_EGR register is used as trigger output (TRGO).

- "OC2REF" : OC2REF signal is used as trigger output.
- "OC3REF" : OC3REF signal is used as trigger output.
- "OC4REF" : OC4REF signal is used as trigger output.
