How is bus lockup avoided?(a) timer and polling(b) combined format(c)

1.	How is bus lockup avoided?(a) timer and polling(b) combined format(c) terminal counter(d) counterThe question was asked in an interview.This interesting question is from I2C-II topic in section Basic Peripherals of Embedded Systems
Answer» The correct ANSWER is (a) TIMER and polling Best explanation: The timeout value can be changed by the PERIPHERAL DEVICES, so for a sophisticated system a COMBINATION of polling and timer is used to check for the signal n times within a predefined interval. This can avoid the bus lock.
