DDRT — Data Direction Register for Timer Port
12.2 Timer Operation in Modes

MOTOROLA
RESET:
Read or write anytime.
The timer forces the I/O state to be an output for each timer port pin associated with an enabled output
compare. In these cases the data direction bits will not be changed but have no affect on the direction
of these pins. The DDRT will revert to controlling the I/O direction of a pin when the associated timer
output compare is disabled. Input captures do not override the DDRT settings.
STOP:
BDM:
WAIT:
NORMAL: Timer keeps running, unless TEN = 0
TEN = 0:
PAEN = 0: All pulse accumulator operations are stopped, registers may be accessed.
0 = Configures the corresponding I/O pin for input only
1 = Configures the corresponding I/O pin for output
