8.3.4 Setting of TCSR Overflow Flag
(1) Setting of TCSR Overflow Flag (OVF): The overflow flag (OVF) is set to 1 when the timer
count overflows (changes from H’FF to H’00). Figure 8-10 shows the timing of this operation.
(2) Timing of TCSR Overflow Flag (OVF) Clearing: The overflow flag (OVF) is cleared when
the CPU writes a 0 in this bit.
