4.7 Parallel Data Interface
The 10 GB C&C Card has a two-way parallel port, through which data
can directly be loaded from IP to the slave device or from the slave device to
IP. Several slave devices can be connected to the bus. The Parallel Data
Interface (PDI) has an 8-bit bi-directional data bus (DATA 0-7) and control
signals: Clock (CLK), Transfer Enable (TE), Read/Write# (RW), IRQ#, WAIT#
and RESET#.

A Read or a Write operation on the Parallel Data Interface can be performed
using PDIREAD or PDIWRITE instructions. (Details about the PDI can be
found in the GEC Instruction Manual Section 4.7)
