1. According to table 12.2, six internal/external clock signals output by prescaler S can be
2. When TCNTV overflows (changes from H'FF to H'00), the overflow flag (OVF) in TCRV0
3. TCNTV is constantly compared with TCORA and TCORB. Compare match flag A or B
4. When a compare match A or B is generated, the TMOV responds with the output value
5. When CCLR1 or CCLR0 in TCRV0 is 01 or 10, TCNTV can be cleared by the corresponding
