Compare Clear Register (CPCR)
The Compare Clear Register (CPCR) is 16-bit register. When this register is matched
with the count value of 16-bit timer, the 16-bit timer is reset to "0000
■ 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
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.
