lpc865m201jhi48 usart0 Driver example initialization part doubt

BerlinRaj — Wed, 22 May 2024 04:04:09 GMT

anyone please verify my code

USART0_Init()

{

uint32_t brgval = 0U;

SYSCON->SYSAHBCLKCTRL0 |= (1<<14);

/* Reset the module. */

SYSCON->PRESETCTRL0 &=~(1<<14);//Assert the usart0 reset

SYSCON->PRESETCTRL0 |= (1<<14);//Clear the usart0 reset

USART0->CFG &= ~(0x30);//NO PARITY

USART0->CFG &= ~(1<<6);//ONE STOP BIT

USART0->CFG &= ~(1<<11);//Asynchronous mode is selected.

USART0->CFG &= ~(1<<6);//ONE STOP BIT

USART0->CFG &= ~(0x3 << 2);//clear 8-bit data length

USART0->CFG |= (0x1 << 2);//set the 8-bit data length

USART0->CFG |= (1 << 14);//usart0 in master mode

USART0->CFG |= (1 << 0);//Enable the uart

brgval = 60000000 / 9600;

base->BRG = brgval - 1U;

//enable Tx

USART0->CFG |= 0X1;

USART0->CTL &= ~(0X40);

}

Recommend you using USART driver under SDK.

Also can refer to the source code.
