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?

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

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.
