LED CONTROL
LEDO will output a frequency while ENLED is in high level. The LEDO output frequency is selected by
option bit LEDF and PLEN condition as described in table 38. When the LEDF is set to 1, the TCTL1
and TCTL2 control pin will also be activated to output the control signal. The TCTL1 and TCTL2 timing
is shown in figure 3.
