KL17, LPUART0/1

Hello,

we have a question to the LPUART0/1 of the KL17: what is the max. possible baudrate ?

A related question to the LPUART0/1 module clock: according to KL17P64M48SF6.pdf, page 22, the max. value is limited to 8 MHz. But according to KL17P64M48SF6RM.pdf, page 66, it can go up to 48 MHz.

With a minimum OSR of 4 we calc the max. Baudrate to be 8/4 = 2 MHz, or 48/4 = 12 MHz. From measurements, the max. Baudrate seems to be 8 MHz. Can someone help clarify this confusion ?

 

Greetings,

 

Wolfram
