TAAnCCR1 - TAA capture/compare register 1
The TAAnCCR1 register is a 16-bit register that operates either both as a
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.TAAnCCS1.
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.
After RESET, TAAnCCR1 register default status is compare register.
RESET input clears this register to 0000H.
When external event counter mode is used, do not set TAAnCCR1 register to
0000H.

• When used as a compare register TAAnCCR1 can be rewritten when
TAAnCE = 1, as below mentioned.
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 a capture register
Count value is stored in TAAnCCR1 upon capture trigger (TIAAn1) input
edge detection.
1.
The value of TAAnCCR1 register can be read/written when TAAnCE bit of
TAAn control register 0 (TAAnCTL0) equals 1.
2.
Access to the TAAnCCR1 register is prohibited when the main clock is
stopped in the subclock mode.
