Description
00: PIN6 will act as GPIO3.
01: PIN6 will act as OVT#
10: PIN6 will act as voltage fault function
11: PIN6 will function as operating clock input function. The external clock
should be 24/48MHz. This input clock will be the clock source of the
whole chip
0: The OVT is low active.(default)
1: The OVT is high active.
OVT queue is used to filter the temperature noise, it define the times of
the event when OVT# is asserted.
00: 1 times
01: 3 times
10: 5 times
11: 7 times
0: The voltage fault is low active.(default)
1: The voltage fault is high active.
Voltage fault queue. It is used to filter the voltage noise, the follow define
the times of the event when VOLT_FAULT# is asserted.
00: 1 times
01: 3 times
10: 5 times
11: 7 times
0: SMI is low active.(default)
1: SMI is high active.
0: OVT asserts according to the Hysteresis limit
1: OVT asserts according to the target limit.
0: The fan fault LED output frequency will be 0.5Hz.(default)
1: The fan fault LED output frequency will be 1Hz.
0: The fan fault will be level mode.
1: The fan fault will indicate by LED function (1Hz or 0.5Hz which is
controlled by LED_FREQ register).
0: The fan fault is low active.(default)
1: The fan fault is high active.
