23.6 Connection with a Debug Tool
23.6.1 About connection with debug tool
Concerning a connection with debug tools, refer to manufactures recommendations.
Debug interface pins contain a pull-up resistor and a pull-down resistor.When debug interface pins are con-
nected with external pull-up or pull-down, please pay attention to input level.
23.6.2 Important points of using debug interface pins used as general-purpose ports
When setting a debugging interface terminal to a general-purpose port by a user's program after reset re-
lease,after that the control from a debugging tool is impossible.
Please note that it is necessary to prepare for the structure which changes the general-purpose port to the de-
bugging interface function by some kind of methods to connect a debugging tool again..
