LPC1768 Embedded Protocols UART, SPI and I2C

In LPC1768, the LCR (Line Control Register) is used to configure which of the following UART settings?

• Baud rate

• Data length, stop bits, and parity

• Transmit and receive buffers

• Interrupt priority

What does the RBR Register in LPC1768 store?

• The UART baud rate

• Data received from the UART

• Data to be transmitted over UART

• UART interrupt flags

In LPC1768 UART , the FDR Register is used for:

• Calculating the UART baud rate more precisely

• Configuring the number of stop bits

• Managing UART interrupts

• Enabling the UART peripheral

Which bit in the LSR indicates that the UART transmit holding register (THR) is empty in LPC1768?

• Bit 0

• Bit 1

• Bit 5

• Bit 7

What is the correct formula for calculating the baud rate in LPC1768's UART?

• Baud Rate = PCLK / (DLL * 16)

• Baud Rate = PCLK / (16 * (DLL + DLM))

• Baud Rate = PCLK / (16 * (DLL + (DLM << 8)))

• Baud Rate = PCLK / (DLL * FDR)

In LPC1768, which UART register is responsible for indicating that a framing error has occurred?

• LSR

• LCR

• IER

• RBR

If DLL = 0x01 and DLM = 0x00, what is the baud rate for UART in LPC1768 when PCLK = 1 MHz?

• 1 Mbps

• 9600 bps

• 115.2 kbps

• 62.5 kbps

In LPC1768 UART, the FCR Register is used to:

• Control the FIFO buffer size

• Enable or disable the FIFO buffers

• Configure the baud rate

• Set parity and stop bits

What is the correct sequence to initialize UART0 in LPC1768 C programming?

• Configure PCONP, PINSEL0, LCR, DLM/DLL

• Configure PCONP, PINSEL1, FCR, THR

• Configure PINSEL0, PCONP, LCR, RBR

• Configure DLM/DLL, THR, PCONP, RBR

In LPC1768 UART C programming, what does the following line configure for UART2?

UART2->LCR = (3 << 0) | (1 << 7);

• 8-bit data length and divisor latch access

• 7-bit data length and enable interrupts

• 8-bit data length and enable parity

• 8-bit data length and disable interrupts
