7.2 POWER MANAGEMENT FUNCTIONS
The W83L197R-16 may be disabled in the low state according to the following table in order to reduce
power consumption. All clocks are stopped in the low state, but maintain a valid high period on
transitions from running to stop. The CPU and PCI clocks transform between running and stop by
waiting for one positive edge on PCICLK_F followed by negative edge on the clock of interest, after
which high levels of the output are either enabled or disabled.
