Note
TAAnCCR0 - TAA capture/compare register 0
The TAAnCCR0 register is a 16-bit register that operates either as capture
register or as a compare register.
In free-running mode, this register can be used as a capture register or as a
compare register specified by bit TAAnOPT0.TAAnCCS0.
In the pulse width measurement mode, this register can be used only as a
capture register (the compare function cannot be used.)
In all modes other than free-running mode and pulse width measurement
mode, this register is used as a compare register.
This register can be read/written in 16-bit units.
After a RESET, TAAnCCR0 register default status is compare register.
RESET input clears this register to 0000H.
When external event counter mode is used, do not set TAAnCCR0 register to
0000H.

• When used as a compare register, TAAnCCR0 can be rewritten when
TAAnCE = 1, as shown below:
TAA operation mode
PWM mode, external trigger pulse output mode
Free-running mode, external event count mode,
one-shot pulse mode, interval timer mode
Pulse width measurement mode
• When used as capture register, the count value is stored in TAAnCCR0
upon capture trigger (TIAAn0) input edge detection.
1.
The value of TAAnCCR0 register can be read/written when TAAnCE bit of
TAAn control register 0 (TAAnCTL0) equals 1.
2.
Access to the TAAnCCR0 register is prohibited when the main clock is
stopped in the subclock mode.
