DB-25 socket P1 – BDM Interface
The DB-25 socket (male) P1 connects the on-board BDM Interface
Logic to a PC’s printer port. To establish the connection, a standard
DB-25 male-female cable must be used. The cable length must be less
than 2m.
A set of associated jumpers are available to configure the on-board
BDM interface.
Two LED’s display the status of the target. While the phyCORE is
held in debug mode, D11 is illuminating.
