7.4 Timer 2
Timer 2 is a 16-bit Timer/Counter which can operate as either an event timer or an
event counter, as selected by C/T2 in the special function register T2CON. Timer 2
has four operating modes: Capture, Auto-reload (up or down counting), Clock-out,
and Baud Rate Generator which are selected according to
Table 19
using T2CON
(
Table 20
and
Table 21
) and T2MOD (
Table 22
and
Table 23
).
