LPC1768 Timers, PWM, RTC and WDT Peripherals

What is the function of the TCR ( Register) in LPC1768 timers?

• To configure the timer’s prescaler value

• To control the enabling and resetting of the timer

• To set the match values for generating interrupts

• To enable external inputs for capture functionality

Which register is used to specify the frequency at which the Timer Interrupt should be generated in LPC1768?

• Timer Counter (TC)

• Match Control Register (MCR)

• Prescaler Register (PR)

• Match Register (MR)

If Timer1 is configured with a PCLK of 1 MHz and a prescaler value of 9 in the Prescaler Register (PR), what will be the effective frequency of the timer?

• 1 MHz

• 100 kHz

• 10MHz

• 10 kHz

How can you reset the Timer Counter (TC) in LPC1768 after a match condition is reached?

• Set the TC reset bit in the Timer Control Register (TCR)

• Set the MR0R bit in the Match Control Register (MCR)

• Set the corresponding bit in the Prescaler Register (PR)

• Clear the Timer Counter (TC) manually

If Timer2 in LPC1768 is configured with a PCLK of 1 MHz and a prescaler of 49, what will be the value of the timer counter after 5 ms?

• 50

• 100

• 1000

• 5000

The Prescale Register (PR) in the LPC1768 timers is used for which purpose?

• To directly set the delay time

• To divide the PCLK frequency before it reaches the timer

• To store the current timer count value

• To enable the interrupt after the match condition

If Timer0 is configured with PCLK = 1 MHz and PR = 99, how much time elapses for the Timer Counter (TC) to increment by 1?

• 100 µs

• 1 ms

• 10 µs

• 1 s

For Timer1, with PCLK = 4 MHz, PR =3 , and Match Register MR0 = 1000, what is the delay time when the Timer Counter (TC) reaches the match value?

• 100 ms

• 400 ms

• 4 ms

• 1 ms

In the LPC1768 timer, what is the minimum possible delay that can be achieved with PCLK = 1 MHz ?

• 1 µs

• 1 ms

• 1 ns

• 1 s

Which of the following is true about the minimum and maximum delay that can be achieved using LPC1768 timers, assuming a PCLK = 1 MHz and PR = 999?

• 1ms & 65.536 sec.

• 1us & 32.768 sec

• 1ms and 71582 min

• 1us and 1193 days
