The internal CP of the CPU 821xNET is directly connected to the CPU
821x by means of a Dual-Port-RAM. The Dual-Port-RAM is divided into 4
equal segments called page frames.
These 4 page frames are available at the CPU as standard CP interface.
Data is exchanged by means of standard handler blocks (SEND and
RECEIVE).
H1 and TCP/IP communication is controlled by means of connections that
are defined with the ADAM configuration tool WinNCS and are directly
transferred into the CPU via the twisted-pair connection.
