Pin 32
R/W
0 = GPIO6; 1 = PWM2 (Pin 32 is VID5 if VIDs are selected). Default = 1.

Pin 29 (Pin 28,
+1.5V
Monitoring)
(Note 2)
R/W
00 = GPIO8.
01 = +1.5V (measured on Pin 28).
10 = THERM2.
11 = THERM2 (default).(Pin 28 is VID6 if VIDs are selected.)
[7:6]
Pin 28 (Pin 29,
+1.5V
Monitoring)
(Note 3)
R/W
00 = GPIO7.
01 = +1.5V (measured on Pin 29).
10 = THERM1.
11 = THERM1 (default).
1. POR = 0xFC, Lock = Y, SW Reset = Y.
2. +1.5V can be monitored on Pin 28 and 29 only when both are configured as +1.5V inputs. This means that +1.5V is measured on both pins
or on neither. +1.5V monitoring cannot be combined with another function on the other pin. For example, if Pin 29 is configured as +1.5V,
then THERM1 cannot be selected on Pin 28, because they share the same selection bits.
