KE18F WDOG Clock Capability

I was wondering what the max frequency is for the watchdog on the KE18F MCU.  The reference manual has a table to describe the timeout capabilities, and I am confused on the last row of the table on page 716.  It says 20MHz (from bus or external).  I have my bus clock running at 60MHz.  Are these values just examples?  Can I run the watchdog up to the bus clock frequency, or will it max out at 20MHz?
