Type C timer is a 16-bit timer. Most often it is used together with type B timer to form a 32-bit general purpose timer. Timers of this type, if present, in the dsPIC30F family of microcontrollers are denoted as the timer3 module and timer5 module like in dsPIC30F4013 microcontroller. Type C timer has the following specific features:
a type C timer can be concatenated with a type B timer to form a 32-bit timer,
at least one type C timer has the ability to trigger an A/D conversion.
Type C timer functional block diagram is shown in Fig. 4-7.

Pin T3CK does not exist in dsPIC30F4013 devices. The figure shows organization of the timer module of a dsPIC30F6014A device. Also, timer5 module does not have the ability to trigger an A/D conversion.
