12.0 TIMER2/3 FEATURES
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 families of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F Family
Reference Manual”, Section 11. “Timers”
(DS70205), which is available on the Micro-
chip web site (www.microchip.com).
Timer2 is a Type B timer that offers the following major
features:
• A Type B timer can be concatenated with a
Type C timer to form a 32-bit timer
• External clock input (TxCK) is always synchronized
to the internal device clock and the clock
synchronization is performed after the prescaler.
Figure 12-1 shows a block diagram of the Type B timer.
Timer3 is a Type C timer that offers the following major
features:
• A Type C timer can be concatenated with a
Type B timer to form a 32-bit timer
• The external clock input (TxCK) is always
synchronized to the internal device clock and the
clock synchronization is performed before the
prescaler
A block diagram of the Type C timer is shown in
Figure 12-2.
Note: Timer3 is not available on all devices.
