GPIO2 Output Dependencies:
000 = GPIO2 is a digital input that is read from r24h[7].
001 = GPIO2 is a digital manual reset input that asserts RESET when asserted. The state
of GPIO2 is read from r24h[7].
010 = GPIO2 is a digital output that is written to through r24h[6].
011 = GPIO2 is a digital fault output that depends on conditions selected by r25h[6:0].
100 = GPIO2 is a digital output that depends on primary thresholds at the input selected
by r24h[5:3].
101 = GPIO2 is a digital output that depends on primary thresholds at the input selected
by r24h[5:3] and on conditions selected by r25h[6:0].
110 = Reserved
111 = Reserved
GPIO2 Single-Input Primary Threshold Voltage Monitor (r24h[2:0] = 100 or 101 only).
GPIO2 asserts low when the primary threshold of this input is exceeded:
000 = IN1
001 = IN2
010 = IN3
011 = IN4
100 = IN5
101 = IN6
110 = IN7
111 = IN8
GPIO2 Output (write to this bit):
1 = GPIO2 is set high if GPIO2 is configured as an output.
0 = GPIO2 is set low if GPIO2 is configured as an output.
GPIO2 Input (read from this bit):
1 = Indicates that GPIO2 is high regardless if GPIO2 is set as an output or input.
0 = Indicates that GPIO2 is low regardless if GPIO2 is set as an output or input.
