Functional Description
7.4
Timer basic operation
7.4.1
TMCLK in Figure 7.2 is reference clock for operation of the timer. This clock will be divided by prescaler setting and the
counting clock will work. Below figures show the starting point of the counter and the ending of the period point of the
counter in normal periodic mode.
Figure 7.2 Basic start and match operation
The period of timer count can be calculated as below equation.
The period = TMCLK Period * Tn.GRB value.
Match A interrupt time = TMCLK Period * Tn.GRA value.
If Tn.CR1.UAO bit is ‘0’. Tn.CR2.TCLR command will initialize all the registers in timer block and load the GRA and GRB
value into Data0 and Data1 buffer. When you change the timer setting and restart the timer with new setting, it’s
recommended that you should write Tn.CR2.TCLR command before Tn.CR2.TEN command.
(a)
Timer will be reset by match GRB timing and count again from 00
(b)
Timer initialization is done by TCLR command and timer will be started by
TEN command
