Note 1: Most OMAP-L138 SOM-M1 I/O pins are dual-voltage capable; that is, the SOM I/O pins
may be configured to operate at 3.3V or 1.8V. The desired I/O voltage is set via J1.37. See
Section 5.5.2 for more information.
Note 2: At startup, the boot mode is determined by sampling BOOT[0:7] (i.e., LCD_D[8:15]).
Resistors on the SOM pull these pins to a default value. User boards may select alternate boot
modes by pulling selected pins opposite their default value; to do this, the user’s board must use
resistors of much lower impedance than those used on the SOM. User boards must ensure that
other circuits do not drive or load down these pins at startup. Driving/loading these pins at startup
may cause the processor to latch an incorrect boot mode. For compatibility with the SOM-M1
form factor, BOOT[1:4] (LCD_D[9,10,11,12] or J1.3,5,7,9) are connected to BOOTBIT[1:4]
(J3.2,4,12,14) through zero ohm resistors.
