Function
This switch is used in conjunction with the RES switch to place the
device in BOOT mode.
This switch is connected via a 0R link to an IRQ line capable of
waking up the microcontroller device from sleep mode.
This switch is connected via a 0R link to another IRQ line capable of
waking up the microcontroller device from sleep mode.
This switch when pressed resets the 3DK microcontroller.
