Figure 7-12 Programmed timer for questions 24,25, and 26 25. For the timer program of Figure 7-12, assume the Following sequence of events: First PB2 is momentarily pressed closed. Next PB1 is pressed closed for 5 s and released. Next PB2 is pressed closed for 4 s and released. 25-1. as a result, the timer-accumulated value at the End of the sequence would be: a) 5 b) 4 c) 9 d) 0 25-1 25-2. As a result, the output PL would be: a) On for 4 s and off for 5 s. b) On for 5 s and off for 4 s. c) On after the entire sequence has been completed. d) Off after the entire sequence has been completed. 25-2 26. For the timer program of Figure 7-12, assume the following sequence of events First PB2 is momentarily pressed closed. Next PB1 is pressed closed for 3 s and released. Next PB1 is again pressed closed for 6 s and released
