With a 7-bit address field, how many I2C slaves can there be?

Which of the following are TRUE about I2C bus arbitration?

I2C slaves can have either 7-bit or 10-bit addresses.

Which of the following is TRUE about the I2C protocol/bus?

What is the defined clock speed for I2C standard mode?

Which of the following supports synchronuos serial communications? 

What do the following codes do?

UART1->IFLS &= ~((0x07<<3) | (0x07<<0)); // reset bits through mask

UART1->IFLS |= (0x01<<3) | (0x03<<0);

The following are the bit definitions forthe Interrupt FIFO Level Select (IFLS) register:

This question is related to the previous question on UARTIBRD register.

A TM4C123GH6PM micrcontroller has a system clock = 50 MHz. Determine the value to be loaded to the UARTFBRD register to achieve a baud rate of 115,200 bits/s. Assume clock division of 16.  

This question is related to the previous two questions on UARTIBRD & UARTFBRD registers.

A TM4C123GH6PM micrcontroller has a system clock = 50 MHz. What is the error rate percentage (%)  based on the values calculated for the UARTIBRD and UARTFBRD registers?

Give your answer a decimal number in %.
