8.1. Microcontroller Headers
Table 8-1 to show theTable 8-4 microcontroller pin headers and their corresponding microcontroller connections. The header pins
connect directly to the microcontroller pin unless otherwise stated.
* marks pins where a the link to the microcontroller pin is open circuit due to unfitted link (link ID in brackets)
