GPIO1 Output Dependencies:
000 = GPIO1 is a digital input that is read from r22h[7].
001 = GPIO1 is a digital manual reset input that asserts RESET when asserted. The state
of GPIO1 is read from r22h[7].
010 = GPIO1 is a digital output that is written to through r22h[6].
011 = GPIO1 is a digital fault output that depends on conditions selected by r23h[6:0].
100 = GPIO1 is a digital output that depends on primary thresholds at the input selected
by r22h[5:3].
101 =GPIO1 is a digital output that depends on primary thresholds at the input selected
by r22h[5:3] and on conditions selected by r23h[6:0].
110 = Reserved
111 = Reserved
GPIO1 Single-Input Primary Threshold Voltage Monitor (r22h[2:0] = 100 or 101 only).
GPIO1 asserts low when any primary threshold of this input is exceeded:

GPIO1 Output (write to this bit):
[6]
1 = GPIO1 is set high if GPIO1 is configured as an output.
0 = GPIO1 is set low if GPIO1 is configured as an output.
GPIO1 Input State (read from this bit):
[7]
1 = Indicates that GPIO1 is high regardless if GPIO1 is set as an output or input.
0 = Indicates that GPIO1 is low regardless if GPIO1 is set as an output or input.
