4. If the following programs are executed, the response time of X0 ~ X7 will be set to 0ms.
However, the fastest response time of input terminals will be 50μs due to that all terminals are
connected with RC filters..

5. It is not necessary to adjust response time when using high-speed counters or interrupts
6. Using API 51 REFF instruction has the same effect as modifying D1020 and D1021.
