I am using a FRDM-KL03Z board.
The USB port is connected to my Windows PC and I run a putty session to connect to the UART.
115200 baud, 8 bits per char, 1 stop, no parity, no handshake.
I have programmed the LPUART0 like wise.
LPUART0 Clk is from MCGPCLK(internal 48 Mhz), OSR is 15 and the SBR value is also fine.
I see garbage on the terminal when I send chars from the board.
The UART works fine at 9600 baud.
I suspect that the 48 Mhz needs trimming, but where is the IPC_TRIM register?, I could not find any ref to this in the ref manual.
Has anyone tried this ?
