14.0
This family of PIC32MX devices features four
synchronous 16-bit timers (default) that can operate as
a free-running interval timer for various timing applica-
tions and counting external events. The following
modes are supported:
• Synchronous Internal 16-bit Timer
• Synchronous Internal 16-bit Gated Timer
• Synchronous External 16-bit Timer

Two 32-bit synchronous timers are available by
combining Timer2 with Timer3 and Timer4 with Timer5.
The 32-bit timers can operate in three modes:
• Synchronous Internal 32-bit Timer
• Synchronous Internal 32-bit Gated Timer
• Synchronous External 32-bit Timer

Throughout this chapter, references to
registers TxCON, TMRx and PRx use ‘x’
to represent Timer2 through 5 in 16-bit
modes. In 32-bit modes, ‘x’ represents
Timer2 or 4; ‘y’ represents Timer3 or 5.
