The restart mode generates an update event.
1: Update event disable.
Note: When this bit is set to 1, setting UPG bit or the restart mode does not
generate an update event, but the counter and prescaler are initialized.
Master mode control
These bits control the selection of TRGO signal, which is sent in master mode to
slave timers for synchronization function.
000: When a counter reset event occurs, a TGRO trigger signal is output. The
counter resert source:
Master timer generate a reset
The UPG bit in the TIMERx_SWEVG register is set
001: Enable. When a conter start event occurs, a TGRO trigger signal is output.
The counter start source :
CEN control bit is set
The trigger input in pause mode is high
010: When an update event occurs, a TGRO trigger signal is output. The update
source depends on UPDIS bit and UPS bit.
