Timer 2
Timer 2 can operate as either an event timer or as an event counter. This is selected by the
bit C/T2 in the SFR named, T2CON (Table 43 on page 93). Timer 2 has three operating
modes selected by bits in T2CON, according to Table 44 on page 94. The three modes are:
● Capture mode
● Auto re-load mode
● Baud rate generator mode
