14.0
This family of PIC32 devices features four synchronous
16-bit timers (default) that can operate as a free-
running interval timer for various timing applications
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

• Selectable clock prescaler
• Timers operational during CPU idle
• Time base for Input Capture and Output Compare
• ADC event trigger (Timer3 only)
• Fast bit manipulation using CLR, SET and INV

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