hello iam using MCXA153 in this there is no mrt what is the repalcement of mrt ?this is my code and i want to build this in MXCA153 what is the replacemnet of MRT?

void Timing_StartCardClk(uint32_t cardClk) {

startTimer(CARD_CLK_DIV * cardClk);

}

static inline void startTimer(uint32_t value) {

MRT_StartTimer(MRT0, 0, MRT_CHANNEL_INTVAL_LOAD_MASK | value);

triggered = false;

}

void Timing_Init() {

// Setup MRT in One-Shot mode

RESET_PeripheralReset(kMRT_RST_SHIFT_RSTn);

const mrt_config_t conf = {false};

MRT_Init(MRT0, &conf);

MRT_SetupChannelMode(MRT0, 0, kMRT_OneShotMode);

MRT_EnableInterrupts(MRT0, 0, kMRT_TimerInterruptEnable);

NVIC_EnableIRQ(MRT0_IRQn);

}

Hi @syedhashmiraza

The MCXA153 does not include an MRT peripheral. To achieve similar functionality, you can use the CTIMER available on the MCXA153.

CTIMER can operate in various modes, including timer mode, which is suitable for generating delays or triggering events like the MRT.

You can refer to the MCXA153SDK ctimer example.

Hi @syedhashmiraza

If you want to use LPTMR,

You can refer to the SDK LPTMR examples.
