Reserved. Unknown during a Read operation.
Timer enable bit. This bit must be set to “1” to enable the
timer. When the timer is disabled, its clock sources are
turned off. Before re-enabling the timer, its Load register
must be written to again.
This bit sets the mode of operation of the timer. When set
to 1, the timer is in periodic timer mode and when set to
“0”, the timer is in free running mode.
When set to “1”, the 508 kHz clock is selected and when
set to “0”, the 2 kHz clock is selected.
