SBC BL2600
The PD0, PD1, PE0, and PE2 signals are configured on the RabbitCore module, and not on
the BL2600. These parallel-port bits are configured for Ethernet on RabbitCore modules
with Ethernet and for output low on RabbitCore modules without Ethernet. The signals are
not available on the BL2600 for customer use in applications.
