Compare Clear Register (CPCLRH, CPCLRL)
The compare clear buffer register (CPCLRBH, CPCLRBL) is a 16-bit buffer register
which exists in the compare clear register (CPCLRH, CPCLRL).
Both the CPCLRBH, CPCLRBL register and the CPCLRH, CPCLRL register exist in the
same address.

Address: 0000A4
Compare clear buffer register (Lower)
CPCLRBL
The compare clear buffer register is a buffer register which exists in the same address of the compare clear
register (CPCLRH, CPCLRL). When the buffer function is disabled (the lower of the timer state control
register (TCCSL), BFE: bit7 = 0), or the free-run timer is stopped, the value of the compare clear buffer
register is transferred to the compare clear register immediately. If the buffer function is enabled, the value
is transferred to the compare clear register when the count value 0 of the 16-bit free-run timer is detected.
To access this register, use a halfword or word access instruction.
