FANIN1/GPO1, FANIN2/GPO2 and BEEP/GPO3 Control Register -- Index 52h,,continued.
BIT NAME
0 EN_GPO1
READ/WRITE
Read/Write
DESCRIPTION
Enable GPO1 Function. Which enable multiple function pin
1, named FANIN1/GPO1, GPO1 function. Set to 0 (default),
pin 1 (FANIN1/GPO1) acts as FANIN1 whcih is fan clock
input. Set to 1, this pin 1 acts as GPO1 control function and
the output value of GPO1 is programmed by this register bit
1. This output pin GPO2 can connect to power PMOS gate to
control FAN ON/OFF.

5 PWM2_LM_Enable Read/Write
Set 1, PWMOUT2 duty cycle will decrease to CR
[89h] when temperature goes below target range.
Set 0, PWMOUT2 duty cycle will decrease to 0 when
temperature grows below target range.
4 PWM1_LM_Enable Read/Write
Set 1, PWMOUT1 duty cycle will decrease to CR
[88h] when temperature goes below target range.
Set 0, PWMOUT1 duty cycle will decrease to 0 when
temperature grows below target range.
