DEBUG Mode
The operating characteristics of the devices in DEBUG mode are:
•
•
•
•
•
Entering DEBUG Mode
The device enters DEBUG mode following the operations below:
•
•
Holding the DBG pin Low for an additional 5000 (minimum) clock cycles after reset
(making sure to account for any specified frequency error if using an internal oscillator)
prevents a false interpretation of an Autobaud sequence (see
