COPPERTAIL
NOTE: 1. Values are only cleared by SB_POWEROK (cold-boot) to preserved state in case of a catastrophic event. Values
preserved during warm-boot.
2. Values are dependent upon core frequency. These values are good for 33 MHz only.

SMB Slave Address. The I/O Controller SMB Slave interface
will respond on the SMB bus to this address. Although this
address contains 8 bits, only bits 7:1 are used for address
comparison. Bit 0 indicates Read/Write.

SMB Slave Acknowledge Count. Programmable count for
SMB input capture window. This count determines where in
the valid data window the SMB_DATA line is sampled.

SMS Enable. When set, the SMB slave is enabled. When clear,
the SMB slave will not respond on the SMB bus.

7:1
Upper byte of Timeout Counter, Bit 9 and these bits make up
the Timeout Count that is used to determine if the SMB bus
should time-out. In the time-out case, the SMB Slave must get
off the bus to allow the SMB Master to generate a SMB stop.
For example, for an Upper count of 1F4h: the 1 is set in bit 9,
F4h is setup in 7:1.
