AT91EB55 Evaluation Board User Guide
Configuration
Straps (CB1 – 15,
JP1 – 9)
By adding the I/O and EBI expansion connectors, users can connect their own peripher-
als to the evaluation board. These peripherals may require more I/O lines than available
while the board is in its default state. Extra I/O lines can be made available by disabling
some of the on-board peripherals or features. This is done using the configuration straps
detailed below. Some of these straps present a default wire (notified by the default men-
tion) that must be cut before soldering the strap.

ADC0 Trigger Input Command
ADC0 trigger input (AD0TRIG) is controlled by the PA4 PIO line.
ADC0 trigger input (AD0TRIG) is not connected to the PA4 PIO line. This
authorizes users to connect the corresponding lines to their own resources via
the I/O expansion connector.
ADC1 Trigger Input Command
ADC1 trigger input (AD1TRIG) is controlled by the PA7 PIO line.
ADC1 trigger input (AD1TRIG) is not connected to the PA7 PIO line. This
authorizes users to connect the corresponding lines to their own resources via
the I/O expansion connector.
On-board NCS4 Signal
This authorizes users to connect the EBI expansion connector of this board to
the MPI expansion connector of an AT91EB63 evaluation board without
conflict problems.
NCS4 signal is connected to the EBI expansion connector (P1 – B21)
NCS4 signal is not connected to the EBI expansion connector (P1 – B21).
