Bus contention arises when more than one register output is "enabled" at the same time on a single data bus line. This condition will cause:
A) uncertain logic levels and possible damage to the register output buffers.
B) uncertain logic levels and possible damage to the input data lines of the registers contending for the bus.
C) uncertain logic levels and possible damage to the bus line.

Question

Quizplus · Accepted Answer

Bus contention leads to uncertain logic levels because multiple outputs are trying to drive the bus to different levels simultaneously. This can also cause damage to the register output buffers due to the conflicting signals.
