LPC54113 UART0 transmission is not working.

PK_1114 — Sat, 23 Dec 2023 05:43:13 GMT

Hello I am using UART0 in my code. When I run the code it is not transmitting any data to UART0.

And also I am not using any interrupts for transmission.

Designed the UART0 functionality with PIO0_21(TX) and PIO0_22(RX). I configured the peripheral and also initialized the pins with UART Functionality, but data transferring not done.

Configuration:

SYSCON -> AHBCLKCTRL[1] |= 1<<11;
IOCON->PIO[0][22] = 0x182;
IOCON->PIO[0][21] = 0x582;
IOCON->PIO[0][20] = 0x182;
FLEXCOMM0 ->PSELID = 0X11;

//CONFIGUE USART
USART0 -> CFG = 0X00;
USART0-> CFG |= 1<<2;
USART0-> OSR = 12;
USART0 -> BRG = 768;
USART0 -> CFG |= (1<<0)|1<<15;

Can anyone can hep me this?
