R= Read only RW= Read and Write 2. PWD = Power on Default 3. The purpose of this bit is to allow a system designer to implement PCI_STOP functionality in one of two ways. Wither the system designer can choose to use the externally provided PCI_STOP# pin to assert and de-assert PCI_STOP functionality via SMBus Byte 0 Bit 3. In Hardware mode it is not allowed to write to the SMBus Byte 0 Bit3. In Software mode it is not allowed to pull the external PCI_STOP pin low. This avoids the issues related with Hardware started and software stopped PCI_STOP conditions. The clock chip is to be operated in the Hardware or Software PCI_STOP mode ONLY , it is not allowed to mix these modes. In Hardware mode the SMBus byte 0 Bit 3 is R/W and should reflect the status of the part. Whether or not the chip is in PCI_STOP mode. Functionality PCI_STOP mode should be entered when [(PCI_STOP#=0) or (SMBus Byte 0 Bit 3 = 0)].

- ICS clock sends first byte (Byte 0) through byte 6
- Controller (host) will need to acknowledge each byte
- Controller (host) will send a stop bit 1. The ICS clock generator is a slave/receiver, SMBus component. It can read back the data stored in the latches for verification. Read-Back will support Intel PIIX4 "Block-Read" protocol. 2. The data transfer rate supported by this clock generator is 100K bits/sec or less (standard mode) 3. The input is operating at 3.3V logic levels. 4. The data byte format is 8 bit bytes. 5. To simplify the clock generator SMBus interface, the protocol is set to use only " Block-Writes" from the controller. The bytes must be accessed in sequential order from lowest to highest byte with the ability to stop after any complete byte has been transferred. The Command code and Byte count shown above must be sent, but the data is ignored for those two bytes. The data is loaded until a Stop sequence is issued. 6. At power-on, all registers are set to a default condition, as shown.

IDTTM Frequency Generator with 133MHz Differential CPU Clocks 0601G—01/26/10 ICS932S203 Frequency Generator with 133MHz Differential CPU Clocks All 3V66 clocks are to be in phase with each other. All 66MHz_OUT clocks are to be in phase with each other. There is NO phase relationship between the 3V66 clocks and the 66MHz_OUT and PCI clocks. In the case where 3V66_1 is configured as 48MHz VCH clock, there is no defined phase relationship betw een 3V66_1/VCH and other 3V66 clo cks. The PCI group should lag 3V66 by the standard skew described below as Tpci.

The impact of asserting the PCI_STOP# signal will be the following. All PCI[6:0] and stoppable PCI_F[2,0] clocks will latch low in their next high to low transition.

IDTTM Frequency Generator with 133MHz Differential CPU Clocks 0601G—01/26/10 ICS932S203 Frequency Generator with 133MHz Differential CPU Clocks When PD# is sampled low by two consecutive rising edges of CPU clock then all clock outputs except CPU clocks must be held low on their next high to low transition. CPU clocks must be held with the CPU clock pin driven high with a value of 2x Iref, and CPUC undriven. Note the example below shows CPU = 100MHz, this diagram and description is applicable for all valid CPU frequencies 66, 100, 133, 200MHz. Due to the state of the internal logic, stopping and holding the REF clock outputs in the LOW state may require more than one clock cycle to complete.
