MSP430FR2153: eUSCI UART mode, max baud rate

Genius 17485 points
Part Number: MSP430FR2153


Hello,

 

I want to confirm eUSCI UART mode specification of FR2153.

 

The datasheet specifies f_BITCLK max is 5MHz.

 

Now I want to realize 5M Baud with 24MHz BRCLK.

In this case, UCBR=4, UCBRS=0xEE looks good configuration.

But this configuration means mixing (6MHz x 2clock) and (4.8MHz x 6 clock).

2 of 8 clock is over 5MHz. Is it allowable?

 

Regards,

Oba
