14.1.2
Both auxiliary timers T2 and T4 have exactly the same functionality. They can be
configured for timer, gated timer, counter, or incremental interface mode with the same
options for the timer frequencies and the count signal as the core timer T3. In addition to
these 4 counting modes, the auxiliary timers can be concatenated with the core timer, or
they may be used as reload or capture registers in conjunction with the core timer.
The individual configuration for timers T2 and T4 is determined by their bitaddressable
control registers T2CON and T4CON, which are both organized identically. Note that
functions which are present in all 3 timers of timer block 1 are controlled in the same bit
positions and in the same manner in each of the specific control registers.
Run control for auxiliary timers T2 and T4 can be handled by the associated Run Control
Bit T2R, T4R in register T2CON/T4CON. Alternatively, a remote control option (T2RC,
T4RC = ’1’) may be enabled to start and stop T2/T4 via the run bit T3R of core timer T3.
Timers T2 and T4 in Timer Mode or Gated Timer Mode
When the auxiliary timers T2 and T4 are programmed to timer mode or gated timer
mode, their operation is the same as described for the core timer T3. The descriptions,
figures and tables apply accordingly with two exceptions:

Note: This example shows the timer behavior assuming that T3 counts upon any
information on the sensor’s current position. Dynamic information (speed,
acceleration, deceleration) may be obtained by measuring the incoming signal
periods.
