In this mode, the timer counts an external signal or an internal timer’s overflow. Timers A0 and A1 can count a single-
phase external signal. Timers A2, A3, and A4 can count a single-phase and a two-phase external signal. Table
lists timer specifications when counting a single-phase external signal. Figure 1
in event counter mode.

Note 1: This bit is valid when only counting an external signal.
Note 2: Set the corresponding function select register A to I/O port, and port direction

Value written to timer Ai register is written to both reload register and counter
Value written to timer Ai register is written to only reload register
