IO, 3V CMOS
General Purpose Input/Output.
182
BOOT_MODE0
BOOT_MODE0/
C12
I, 3.3V CMOS/
4.7K PU
Boot Mode Select bit0.
Important Note: This pin is directly
connected to i.MX6 CPU’s BOOT_MODE0 pin
with On-
SOM pullup and so don’t add any
external pullup in carrier board on this pin.
Make sure to use this pin in carrier board to
select desired boot mode by driving only low
if required.
183
VRTC_3V0
NA
I, 3V Power
3V backup coin cell input for RTC.
184
BOOT_MODE1
BOOT_MODE1/
F12
I, 3.3V CMOS/
4.7K PU
Boot Mode Select bit1.
Important Note: This pin is directly
connected to i.MX6 CPU’s BOO
T_MODE1 pin
with On-
SOM pullup and so don’t add any
external pullup in carrier board on this pin.
Make sure to use this pin in carrier board to
select desired boot mode by driving only low
if required.
