Target board pin headers
The Target Board pin headers, J1, J2, J3, and J4, provide access to all Main MCU interface signals, and to voltages for
all Main MCU power ports.
Fixed Function Pin Assignments
For consistency across all Synergy Target Board Kits, some pin assignments on the headers have
fixed function
signal
assignments. This provides specific signals and functions to be at a common pin header location on all Target Boards
for a Synergy MCU Group (e.g. S1/S3/S5/S7) and where possible, across all Synergy MCU Target Boards.
On the TB-S3A1, 40 pins of the pin headers are set aside for
fixed function
assignment. These pins are odd-numbered
pins of J1 and even-numbered pins of J2.
Pin Header Fixed Function Pins are labeled on the Target Board with dark text on a white background. Pins that are not
Fixed Function pins are labeled with white text on a dark background. On the top side of the board is the functional
label for the fixed location. On the bottom side of the board is the port information for the same pin.
