Description:
Reading returns the list possible master modes which are:
- - "reset" : The UG bit from the TIMx_EGR register is

+ - "reset"
+ The UG bit from the TIMx_EGR register is
used as trigger output (TRGO).
- - "enable" : The Counter Enable signal CNT_EN is used
+ - "enable"
+ The Counter Enable signal CNT_EN is used
as trigger output.
- - "update" : The update event is selected as trigger output.
+ - "update"
+ The update event is selected as trigger output.
For instance a master timer can then be used
as a prescaler for a slave timer.
- - "compare_pulse" : The trigger output send a positive pulse
- when the CC1IF flag is to be set.
- - "OC1REF" : OC1REF signal is used as trigger output.
- - "OC2REF" : OC2REF signal is used as trigger output.
- - "OC3REF" : OC3REF signal is used as trigger output.
- - "OC4REF" : OC4REF signal is used as trigger output.
