Description
Timer 2 Up / Down Control
(when T2UDE = ’0)
Counting ’Up’
Counting ’Down’
Timer 2 External Up/Down Enable
Counting direction is internally controlled by
SW
Counting direction is externally controlled by
line T2EUD
Pin P3.5 connected to T2EUD is also
connected to T4IN and to T3EUD.
Timer 2 Remote Control
Timer / Counter 2 is controlled by
its own run bit T2R
Timer / Counter 2 is controlled by
the run bit of core timer 3
reserved for future use; reading returns 0;
writing to these bit positions has no effect.
Timer 2 Edge Detection
The bit is set on each successful edge
detection. The bit has to be reset by SW.
No count edge was detected
A count edge was detected
Timer 2 Count Direction Change
The bit is set on a change of the countdirection
of timer 2. The bit has to be reset by SW.
No change in count direction was detected
A change in count direction was detected
Timer 2 Rotation Direction
Timer 2 counts up.
Timer 2 counts down.
Timer 2 Interrupt Enable
Interrupt generation for T2CHDIR and
T2EDGE is disabled.
Interrupt generation for T2CHDIR and
T2EDGE is enabled.
