LPC824 to LPC84x

Will0328 — Tue, 07 Nov 2023 11:15:24 GMT

In the LPC824 based project, I used the following code to initialize the UART：

LPC_SWM->PINASSIGN[0] &= ~( 0xFFFF << 0 );
LPC_SWM->PINASSIGN[0] |= ( 4 << 0 );
LPC_SWM->PINASSIGN[0] |= ( 0 << 8 );
LPC_SYSCON->UARTCLKDIV = 1;
LPC_SYSCON->SYSAHBCLKCTRL |= (1 << 14);
...............

But I couldn't find the definition of UARTCLKDIV in the syscon of LP844.h and LP845.h files.

Hello @Will0328

They are not the same, please refer to UART demo for LPC845 under SDK.
