Input parameters
STMR_Prescaler specifies the
prescaler division factor for the
STMR. It can be a power of two
ranging from 1 to 128.
STMR_Period specifies the period to
be set for the timer interrupt
generation.
NewState: it can be ENABLE or
DISABLE.
STMR_IT specifies whether the
STMR interrupt must be enabled or
disabled.
NewState can be ENABLE or
DISABLE.
Newstate can be ENABLE or
DISABLE.

counter overflow only or by registers
update. Possible values are
UPDATESOURCE_GLOBAL and
UPDATESOURCE_REGULAR.
STMR_OPMode specifies if the one
pulse mode must be activated.
