Currently all PIC Microcontrollers used by Netcruzer boards have 5 16-bit timers, Timer 1 to 5.

Timer 2, and possibly 3, is used for the system tick. The default system tick implementation nz_tick.c only uses Timer 2, so timer 3 is actually not used. But, future tick implementations might use cascaded 32-bit system tick, in which case Timer 2 and 3 will be used.

User applications can use Timer 1, 4, and 5. Timer 4 and 5 can be used as individual 16-bit timers, or can be combined to form a 32-bit timer.
