Remark:
Note: The value of TPnCCR1 register is read when TPnCE bit of TMPn control register 0 (TPnCTL0)

TMP capture/compare register 1 (TPnCCR1)
The TPnCCR1 register is a 16-bit register that operates either both as a capture register or as a
compare register.
Whether this register is used as a capture register or as a compare register can be specified with
the TPnCCS1 and TPnCCS0 bits of the TMPn option register 0 (TPnOPT0 register), but only in
free-running mode.
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, TPnCCR1 register default status is compare register.
RESET input clears this register to 0000H.
• When used as a compare register
TPnCCR1 can be rewritten when TPnCE = 1, as below mentioned.
• When used as a capture register
Count value is stored in TPnCCR1 upon capture trigger (TIPn1) input edge detection.

When external event counter mode is used, do not set TPnCCR1 register to 0000H.
