Capture/compare register 1 (TQnCCR1)
The TQnCCR1 register is a 16-bit register that has a capture function and a compare function.
Whether this register is used as a capture register or a compare register can be specified by using
the TQnCCS1 bit of the TQnOPT0 register, but only in the free-running mode.
In the pulse width measurement mode, this register can be used only as a capture register (it
cannot be used as a compare register).
In all the modes other than the free-running mode and pulse width measurement mode, this
register functions as a compare register.
In the default status, the TQnCCR1 register functions as a reload register.
This register can be read or written in 16-bit units.
RESET input clears this register to 0000H.
• When used as a compare register
TQnCCR1 can be rewritten when TQnCE = 1, as below mentioned:
• When used as a capture register
The count value is stored in TQnCCR1 upon capture trigger (TIQn1) input edge detection.

In the one-shot pulse mode, it is prohibited to set the TQnCCR1 register to 0000H.
