8.5.4 Timing in the Synchronous Motorola Mode (E_Clock-Mode, for example, 68HC11) :

For a CPU clockline through the SPC3, the output clock pulse (CLKOUT2/4) must be 4 times larger than the E_CLOCK. That is, a clock pulse signal must be present at the CLK input that is at least 10 times larger than the desired system clock pulse (E_CLOCK). The Divider-Pin must be placed on <log. 0> (divider 4). This results in an E_CLOCK of 3MHz.
