NOTE
If no physical signal is applied to the external input or if a function other than “External
input” is selected for pin 2 configuration (ISDU 121), the status of the external input is
interpreted as logical 0.

Timer 1/2 mode can be used to select various delay modes.
The relevant delay time is selected under Time 1/2 setup.
See the following graphic for details on how the different modes work.

Inverter 1/2 inverts the logical condition of the timer 1/2 output signal.
NOTE
Inverting the Timer 1/2 output signal does not affect how the delay modes work.
Note that due to the inversion of the Timer 1/2 output signal, a set switch-on delay, for
example, can act like a switch-off delay.
