QG8-use of PTB6 as XTAL o/p

   I'm in need of a 32.768kHz clock for an auxilliary chip. Chapter 10 of the data sheet(ICS module) seems to indicate that there is a XTAL signal available at PTB6 which is sourced from the Low Power Oscillator (figure 10-1). Can this be used as a source for the 32.768k clock if the osc is trimmed correctly. The only clock critical issue is a needing 19200 baud for external comms. I can find no reference to XTAL/PTB6 except on this figure.

I'm new to this processor so excuse me if I'm missing something.
