with the count value of 16-bit timer, the 16-bit timer is reset to "0000
H
".

Compare Clear Register (CPCR)
Compare Clear Register is a 16-bit register and is used to compare the count value of the 16-bit timer. The
initial value of this register is undetermined, so that the register must be set a value before starting an
operation.
Notes:
Word access instruction to this register must be used.
When this register is matched with the count value of 16-bit timer, 16-bit timer is reset to "0000
H
"
and the compare clear interrupt flag is set. Furthermore, when the interrupt operation is enabled,
interrupt request is sent to the CPU.
If the Compare Clear Register (CPCR) is loaded a value same as the Timer Counter value at that
moment, the comparison operation will NOT be performed until next same counter value.
