Hi,

Please help me on this:

My doubt in "void lptmr_isr(void)" , in step-1 : we are writing to the peripheral register LPTMR0_CSR ,

to ensure that LPTMR0_CSR register has been written successfully , how the next statement , means

in step -2:dummy_var = LPTMR0_CSR;

is ensuring that the desired value has been written successfully.

are we performing the read operation just for "to elapsed some time? i mean its a dummy instruction ,which only aim to pass some

time (means wait) so that "write operation" done during the execution of this instruction.
