Hi

I would like help finding out these answers please.

What is the purpose of a start bit? Select one a. It transfers the first data bit of the character being sent, from the sender to the receiver b. It is used to check if the receiver is ready to start receiving a character. c. It is used to detect errors in the transmission O d. It lets the receiver know that a transmission has started, and data will follow shortly What is true about addresses 0x70000 and 0x71000? Select one a. They both refer to the same physical memory location. b. They perform the same function, but for different serial ports. c. Reading from these addresses will provide the values of the switches and push buttons, respectively d. Writing to these addresses will cause a value to appear on the left and right SSDs, respectively. O What would happen if you write 32 bits into the Left SSD register, assuming that the Hex-SSD Decode Enable bit is on (i.e.'1) Select one a. The upper 24 bits would be ignored, while the lower 8 bits would control individual segments of the left SSD. b. The lower 8 bits would be stored in the Left SSD Register, while some of the upper 24 bits would overflow into the Right SSD Register c. Writing 32 bits into an 8-bit register is not recommended, and the result is largely unpredictable. d. The upper 28 bits would be ignored, while the lower 4 bits would appear on the left SSD as a hexadecimal digit
