Setup (MD) Button (Line)

Tibbo boards and external controllers (such as the EM2001 and DS1101) have a button called "setup" or "MD" button ("MD" abbreviation stands for "mode"). Tibbo modules (such as the EM2000) have an MD pin (line).

The setup button (line) has three functions:

• When a Tibbo BASIC/C application is running, it can use the button for its own purposes (see the button. object).

• When the device is password-protected , keeping the button pressed (line pulled LOW) while accessing the device from TIDE allows bypassing the password. This is the way to reset the password on the device.

• When the device is powered up (exits from the hardware reset) with the button pressed (line pulled LOW), it boots into the Monitor/Loader and enters a firmware update mode.
