-Refer to Figure 9- 11. The output of the counter is checked and found to be 50 kHz. Is the counter working correctly? If not, what could be wrong?
A) The counter is defective; there is probably a bad connection on the CTEN terminal of CTR0.
B) The counter is defective; an open exists somewhere between TC of CTR0 and CTEN of CTR1.
C) The counter is working correctly.
D) The counter is not working correctly; the TC of CTR1 is probably shorted to ground.
