CHAPTER 7 16-BIT TIMER/EVENT COUNTER AA (TAA)
Figure 7-38. Software Processing Flow in Free-Running Timer Mode (Capture Function) (2/2)
<1> Count operation start flow
START
Register initial setting
TAAnCTL0 register
(TAAnCKS0 to TAAnCKS2 bits),
TAAnCTL1 register,
TAAnIOC1 register,
TAAnOPT0 register
Initial setting of these registers
is performed before setting the
TAAnCE bit to 1.
TAAnCE bit = 1
The TAAnCKS0 to TAAnCKS2 bits can
be set at the same time when counting
has been started (TAAnCE bit = 1).
<2> Overflow flag clear flow
Read TAAnOPT0 register
(check overflow flag).
NO
TAAnOVF bit = 1
YES
Execute instruction to clear
TAAnOVF bit (CLR TAAnOVF).
<3> Count operation stop flow
TAAnCE bit = 0
Counter is initialized and
counting is stopped by
clearing TAAnCE bit to 0.
STOP
Remark n = 0 to 5
