compare register whose value is to be compared with that of the 8-bit timer counter H1 is changed from the
CMP01 register to the CMP11 register.
H1 is operating. The new value (L) to which the value of the register is to be changed is latched. When the
count value of the 8-bit timer counter H1 matches the value (M) of the CMP11 register before the change, the
CMP11 register is changed (<3>’).
However, it takes three count clocks or more since the value of the CMP11 register has been changed until
the value is transferred to the register. Even if a match signal is generated before the duration of three count
clocks elapses, the new value is not transferred to the register.
