1.	Which of the following are not used within the IBM PC?(a) TXRDY(b) BAUDOUT(c) ADS(d) OUT2The question was posed to me during an interview for a job.The question is from UART-2 in section Basic Peripherals of Embedded Systems
Answer» CORRECT answer is (a) TXRDY The explanation is: The CPU is responsible for moving data to and from the UART in the IBM PC, THEREFORE it does not have TXRDY and RXRDY pins which are USED for DMA accessing.
