GPIO Port D Expansion Connector3.7 Daughter Card ConnectorThe Control Board includes two daughter card connectors. One connector, J1, contains theprocessor’s peripheral port signals. The second connector, J2, contains the processor’s externalmemory bus signals. The Daughter Card connectors are used to connect the Ethernet evaluationdaughter card; see Figure 3-13.SCRsGATER130 Ohm+3.3VPC1PC0 R120 OhmC830.47uFJ813579246810BYPASSJ41357911132468101214PD10 PD11
