Timer5 is a general-purpose timer/counter that incorpo-
rates additional features for use with the Motion Feed-
back module (see Section 16.0 “Motion Feedback
Module”). It may also be used as a general-purpose
timer or a special event trigger delay timer. When used
as a general-purpose timer, it can be configured to gen-
erate a delayed special event trigger (e.g., an ADC
special event trigger) using a pre-programmed period
delay.
Timer5 is controlled through the Timer5 Control Regis-
ter (T5CON), shown in Register 14-1. The timer can be
enabled or disabled by setting or clearing the control bit
TMR5ON (T5CON<0>).
A block diagram of Timer5 is shown in Figure 14-1.
