16-Bit Timer/Event Counter AA
Figure 10-20
Note
• Select clock.
(TAAnCTL0: TAAnCKS[2:0])
• Set PWM mode.
(TAAnCTL1: TAAnMD[2:0] = 100B)
•
Set compare register.
(TAAnCCR0, TAAnCCR1)
Enable timer operation (TAAnCE = 1)
→ Transfer value of TAAnCCRm
register to CCRm buffer register
16-bit counter matches TAAnCCR1.
TOAAn1 outputs inactive level.
16-bit counter matches TAAnCCR0.
Clear and start 16-bit counter.
TOAAn1 outputs active level.
Rewrite TAAnCCR0.
16-bit counter matches
CCR1 buffer register.
TOAAn1 outputs inactive level.
Rewrite TAAnCCR1.
• CCR0 buffer register matches 16-bit
counter.
• Clear and start 16-bit counter.
• Value of TAAnCCRm is reloaded to
CCRm buffer register.
Flowchart of Basic Operation in PWM Mode
When values of TAAnCCR0, TAAnCCR1 registers are rewritten during
timer operation
1.
The timing of <2> in the above flowchart may differ depending on the
rewrite timing of steps <1> and <3> and the value of TAAnCCR1, but make
sure that step <3> comes after step <1>.
