I meant on this piece of text:

82h Burst Enable:
1. Host writes command byte 82h (Burst_Enable) to port 66h.
2. EC will issue SCI to host while OBF=1.
3. Host reads via port62h. If 90h obtained, it‘s Burst Ack.

 

83h Burst Disable:
1. Host writes command byte 83h (Burst_Disable) to port 66h.
2. EC will issue SCI to host while IBF=0

I quote from the datasheet: "The EMC2103 communicates with a host controller, such as an SIO, through the SMBus. The SMBus.

is a two-wire serial communication protocol between a computer host and its peripheral devices ". Interesting information on the fan control is on page 57:D
