Re: NuMaker-PFM-M2351 UART1 Programming

The UART1 clock is seems to not enabled in your program. Please try to enable UART1 clock and set UART1 clcok source by adding the following codes: /* Select UART1 clock source */ CLK->CLKSEL1 = (CLK->CLKSEL1 & (~CLK_CLKSEL1_UART0SEL_Msk)) | CLK_CLKSEL1_UART0SEL_HIRC; /* Enable UART1 clock */ CLK->A...

Re: IO pin function setting

The first writing method configures PA.9~PA.11 function only.

It is recommonded to use the first method to avoid configuration overwriting.
