DIRECT PORT ACCESS
Direct port access connectors
Example of how to connect
external peripheral with flat
cable
These connectors can be used for system expansion with external boards such as Serial
Ethernet, Compact Flash, MMC/SD, ADC, DAC, CAN, RTC, RS-485, etc. Ensure that the
on-board peripherals are disconnected from microcontroller by setting the appropriate
jumpers, while external peripherals are using the same pins. The connectors can also be used
for attaching logic probes or other test equipment.
All microcontroller input/output pins can be accessed via connectors placed along the right
side of the board. For each of PORTA, PORTB, PORTC, PORTD and PORTE there is one
10-pin connector providing VCC, GND and up to eight port pins.
