DESCRIPTION
Enable GPIO7 Function. Which enable multiple function
pin 7, named SMI#/GPIO7, GPIO7 function. Set to 0
(default), pin 7 (SMI# /GPIO7) acts as SMI# which is fan
count out of the limit value. Set to 1, this pin 7 acts as
GPIO7 control function and the output value of GPIO7 is
programmed by this register bit 5.
GPIO2 Output Value. GPIO2 output value if EN_GPIO2
is set to 1. Write 1, then pin 2 (GPIO2) always generate
logic high signal. Write 0, pin 2 (GPIO2) always generates
logic low signal. This bit default 0.
Enable GPIO2 Function. Which enable multiple function
pin 2, named FANIN2/GPIO2, GPIO2 function. Set to 0
(default), pin 2 (FANIN2/GPIO2) acts as FANIN2 which is
fan clock input. Set to 1, this pin 2 acts as GPIO2 control
function and the output value of GPIO2 is programmed by
this register bit 3. This output pin GPIO2 can connect to
power PMOS gate to control FAN ON/OFF.
GPIO1 Output Value. GPIO1 output value if EN_GPIO1
is set to 1. Write 1, then pin 1 (GPIO1) always generate
logic high signal. Write 0, pin 1 (GPIO1) always generates
logic low signal. This bit default 0.
Enable GPIO1 Function. Which enable multiple function
pin 1, named FANIN1/GPIO1, GPIO1 function. Set to 0
(default), pin 1 (FANIN1/GPIO1) acts as FANIN1 which is
fan clock input. Set to 1, this pin 1 acts as GPIO1 control
function and the output value of GPO1 is programmed by
this register bit 1. This output pin GPIO1 can connect to
power PMOS gate to control FAN ON/OFF.
