How to enter Sleep mode(If Possible deep sleep also) and wake up using LPTMR

sachinjoy — Sat, 06 Jun 2015 12:44:46 GMT

I am Using KL16z64VLH4 with Configuration

SIM_COPC = 0x00U; // DISABLE THE WDOG MODULE

SIM_CLKDIV1 = (SIM_CLKDIV1_OUTDIV1(0x00) | SIM_CLKDIV1_OUTDIV4(0x00)); // SET THE SYSTEM PRESCALERS TO SAFE VALUE --DIVIDE BY 1

SIM_SOPT2 = 0x0000; // SELECT FLL AS A CLOCK SOURCE FOR VARIOUS PERIPHERALS

SIM_SOPT2 |= SIM_SOPT2_UART0SRC(3); // SELECT MCGIRCLK FOR UART0

SIM_SOPT1 |= SIM_SOPT1_OSC32KSEL(00); // EXTERNAL CLOCK ---32 KHZ CLOCK SOURCE FOR RTC

OSC0_CR |= 1<<7; // ENABLES THE OSC CLOCK

MCG_SC = 0X00; // FRCDIV=1

MCG_C1 = 0X46; // SELECT INTERNAL REFERENCE CLOCK

MCG_C2 = 0X01; // FAST INTERNAL REFERENCE CLOCK IS SELECTED

and LPTMR Config

SIM_SCGC5 |= SIM_SCGC5_LPTMR_MASK;

LPTMR0_CSR = 0x00U;

LPTMR0_CMR = 0x00U;

LPTMR0_CMR = LPTMR_CMR_COMPARE(cmp_value);

LPTMR0_CSR = LPTMR_CSR_TCF_MASK;

LPTMR0_PSR = LPTMR_PSR_PRESCALE(13);

NVIC_ISER |= (1 << ((uint32_t)(INT_LPTimer -16) & 0x1F)); // ENABLING THE INTERRUPT

NVIC_ICPR |= (1 << ((uint32_t)(INT_LPTimer -16) & 0x1F));

NVIC_IPR7 = 6;

LPTMR0_CSR |= LPTMR_CSR_TIE_MASK;

LPTMR0_CSR |= LPTMR_CSR_TEN_MASK;

Can any body sugget me a sleep mode and its configuration,
