I have found. It is described on the pages 5-13 and 5-14 of MCF51AC256RM.pdf .

This signal is connected with the bus frequency :

MCLK frequency = Bus clock frequency /(2 * MCSEL) .

In Adobe Acrobat, Control-F will let you search a document for keywords, and Control-Shift-F will bring up a window with all matches. There are 21 matches for "MCLK" (whole word, match case) in the Reference Manual.
