Q:

 What is the maximum baud rate supported by the LEUART when running off a 32kHz crystal oscillator?

A:

 The LEUART baud rate must be set at least 3 times lower than the LEUART clock frequency, which with a 32.768 kHz oscillator gives a maximum baud rate of 10922.7 baud/s. The closest standard baud rate is 9600 baud/s.
