• A shunt connecting J6 pins 1 and 2 selects 1.8 V.
• A shunt connecting J6 pins 3 and 4 selects 2.5 V.
• A shunt connecting J6 pins 5 and 6 selects 3.3 V (default).
Caution: Only select one voltage at a time. Installing more than one
shunt on J6 may cause contention.
J8 Header
J8 is a 2 x 3 (6-pin) header that lets you select 3.3 V, 2.5 V, or 1.8 V for T8F81C
bank 2B VDDIO (VDDI02B) from the on-board regulators.
