Data Sheet
14.2.1
The operation of the core timer T6 is controlled by its bitaddressable control register
T6CON.
Timer 6 Run Bit
The timer can be started or stopped by software through bit T6R (Timer T6 Run Bit).
Setting bit T6R to ‘1’ will start the timer, clearing T6R stops the timer.
In gated timer mode, the timer will only run if T6R = ‘1’ and the gate is active (high or low,
as programmed).
Note: When bit T5RC = ’1’ bit T6R will also control (start and stop) auxiliary timer T5.
Count Direction Control
The count direction of the core timer can be controlled either by software or by the
external input line T6EUD (Timer T6 External Up/Down Control Input). These options are
selected by bits T6UD and T6UDE in control register T6CON. When the up/down control
is done by software (bit T6UDE = ‘0’), the count direction can be altered by setting or
clearing bit T6UD. When T6UDE = ‘1’, line T6EUD is selected to be the controlling
source of the count direction. However, bit T6UD can still be used to reverse the actual
count direction, as shown in the table below. If T6UD = ‘0’ and line T6EUD shows a low
level, the timer is counting up. With a high level at T6EUD the timer is counting down. If
T6UD = ‘1’, a high level at line T6EUD specifies counting up, and a low level specifies
counting down. The count direction can be changed regardless of whether the timer is
running or not.
Table 14-7
Note: The direction control works the same for core timer T6 and for auxiliary timer T5.
