... ICS9248-102 General Description The ICS9248-102 is the single chip clock solution for Desktop/Notebook designs using the SIS 540/630 style chipset. It provides all necessary clock signals for such a system. Spread spectrum may be enabled through I Spread spectrum typically reduces system EMI by 8dB to 10dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding ...

... ICS9248-102 Shared Pin Operation - Input/Output Pins The I/O pins designated by (input/output) on the ICS9248- 102 serve as dual signal functions to the device. During initial power-up, they act as input pins. The logic level (voltage) that is present on these pins at this time is read and stored into a 5-bit internal data latch. At the end of Power-On reset, (see AC characteristics for timing values), the device changes the mode of operations for these pins to an output function ...
