9.5.1.1 Timer unit block diagram
9.5.1 Timer unit implementation
9.5 Timer unit
The timer derives its clock from the 13.56 MHz on-board chip clock. The microprocessor
can use this timer to manage timing-relevant tasks.
The timer unit may be used in one of the following configurations:
The timer unit can be used to measure the time interval between two events or to indicate
that a specific timed event occurred. The timer is triggered by events but does not
influence any event (e.g. a time-out during data receiving does not automatically influence
the reception process). Several timer related flags can be set and these flags can be used
to generate an interrupt.
