1 GPO1_VAL Read/Write
DESCRIPTION
GPO4 Output Value. GPO4 output value if EN_GPO4 is set
to 1. Write 1, then pin 11 (GPO4) always generate logic high
signal. Write 0, pin 11 (GPO4) always generates logic low
signal. This bit default 0.
Enable GPO4 Function. Set to 0 (default), pin 11
(BATFAULT#/GPO3) acts as BATFAULT# whcih is battery
voltage out of the limit value. Set to 1, this pin 11 acts as
GPO4 control function and the output value of GPO4 is
programmed by this register bit 7.
GPO3 Output Value. GPO3 output value if EN_GPO3 is set
to 1. Write 1, then pin 5 (GPO3) always generate logic high
signal. Write 0, pin 5 (GPO3) always generates logic low
signal. This bit default 0.
Enable GPO3 Function. Set to 0 (default), pin 5
(FANFAULT#/GPO3) acts as FAN_FAULT whcih is fan count
out of the limit value. Set to 1, this pin 5 acts as GPO3 control
function and the output value of GPO3 is programmed by this
register bit 5.
GPO2 Output Value. GPO2 output value if EN_GPO2 is set
to 1. Write 1, then pin 2 (GPO2) always generate logic high
signal. Write 0, pin 2 (GPO2) always generates logic low
signal. This bit default 0.
Enable GPO2 Function. Which enable multiple function pin
2, named FANIN2/GPO2, GPO2 function. Set to 0 (default),
pin 2 (FANIN2/GPO2) acts as FANIN2 whcih is fan clock
input. Set to 1, this pin 2 acts as GPO2 control function and
the output value of GPO2 is programmed by this register bit
3. This output pin GPO2 can connect to power PMOS gate to
control FAN ON/OFF.
GPO1 Output Value. GPO1 output value if EN_GPO1 is set
to 1. Write 1, then pin 1 (GPO1) always generate logic high
signal. Write 0, pin 1 (GPO1) always generates logic low
signal. This bit default 0.
