In the following UART frame, what is the parity of the frame?

A UART transmits 7 bits of data with even parity and one STOP bit.

What is the time taken to transmit the UART frame at 115,200 bps?

The following is a UART frame sent. 

What is the ASCII character sent?

How many UARTS are implemented in the TM4C123GH6PM microcontroller?

Which of the following is TRUE about a UART?

The following are defined:

  #define PD2 2U

  #define PD4 4U

  #define PD7 7U

  #define BIT( x )  (1U<<(x))

In this and the next question, write C statements that would enable PD2, PD4 and PD7 to be edge triggered on the rising edge.

For this part of the question, write a C statement for the GPIOIS register (GPIOD->IS) that would accomplish the above. 

GPIOD->IS &= ~xxxxxxxxxxxxxxxx; or GPIOD->IS |= xxxxxxxxxxxxxxxx; // do not leave spaces for the xxxxxxxxxxxxxxx, e.g. (BIT(PD2)|BIT(PD4)).

The following are defined:

  #define PD2 2U

  #define PD4 4U

  #define PD7 7U

  #define BIT( x )  (1U<<(x))

Write a C statement that would enable PD2, PD4 and PD7 to be edge triggered on the rising edge.

For this part of the question, write C statement for the GPIOIS IEV register (GPIOD->IEV) that would accomplish the above. 

GPIOD->IEV &= ~xxxxxxxxxxxxxxxx; or GPIOD->IEV |= xxxxxxxxxxxxxxxx; // do not leave spaces for the xxxxxxxxxxxxxxx, e.g. (BIT(PD2)|BIT(PD4))

Which register would allow us to identify the source of the interrupt?

Select all that applies.

Which of the following is TRUE about edge-triggered interrupts?

Check all that applies.

Which of the following is TRUE about level-triggered interrupts?

Check all that applies.
