19 / 49 page  Fintek Feature Integration Technology Inc. V0.25P 14 F75373 6.2 Configuration Register Index 01h Power on default <7:0> = 00h Bit Name Attribute Description 7-2 Reserved RO Read back will be 0 1 PIN4_MODE R/W Pin 4 mode select, set this bit to 1 will enable PWMOUT2 output, else if set this bit to 0, pin 4 will be enable the GPIO1 function.(default) This mode is trappable: When PIN3 trapped to high at power-on, PIN4 is set to PWMOUT2. When PIN3 trapped to low at power-on, PIN4 is set to GPIO1. 0 PIN2_MODE R/W Pin 2 mode select, set this bit to 1 will enable FANIN2 input, if set this bit to 0 pin 2 will be enable the GPIO0 function.(default). This mode is trappable: When PIN3 trapped to high at power-on, PIN2 is set to FANIN2. When PIN3 trapped to low at power-on, PIN2 is set to GPIO0. 6.3 Configuration Register Index 02h Power on default <7:0> = 00h Bit Name Attribute Description 7-6 PIN5_MODE R/W 00: pin5 function is GPIO2 01: pin5 is used as SMI 10: pin5 is used as Fan fault function 11: LED out(1Hz/0.5Hz select by bit2) 5 SMI_MODE R/W If set to 0, SMI will be level mode else if this bit set to 1, SMI will be pulse mode. 4 SMI_LEVEL R/W When set this bit to 0 SMI is low active (default). if set to 1 SMI is high active 3 Reserved R/W Reserved register 2 LED_FREQ R/W When set this bit to 1 fan fault LED output frequency will be 0.5HZ, else is 1Hz(default) 1 F_FAULT_MOD E R/W When set this bit to 0 the fan fault will be level mod, else if set to 1 the fan fault will indicate by LED function(1Hz or 0.5Hz) the LED frequency can set by REG02H bit2 |
