Note: The external microcontroller should not attempt to access the Intel
Note: When an external microcontroller accesses the SMBus Slave Interface over the SMLink
SMBus slave logic until 1 second after both: RTEST# is high and RSMRST# is high.
When a master leaves the clock and data bits of the SMLink interface at ‘1’ for 50 µs or
more in the middle of a cycle, the Intel
undefined. This is interpreted as an unexpected idle and should be avoided when
performing management activities to the slave logic.
a translation in the address is needed to accommodate the least significant bit used for
read/write control. For example, when the Intel
(RCV_SLVA) is left at 44h (default), the external microcontroller would use an address
of 88h/89h (write/read).
The external master performs Byte Write commands to the Intel
