In this process, Timer A0 and Timer A1 are connected to make a 16-bit timer with a 16-bit
prescaler. Figure 3.1.1 shows the operation timing, Figure 3.1.2 shows the connection dia-
gram, and Figures 3.1.3 and 3.1.4 show the set-up procedure.
Use the following peripheral functions:
(1) Set timer A0 to timer mode, and set timer A1 to event counter mode.
(2) Perform a count on count source f
(3) Connect a 16-MHz oscillator to X
