10
The Bus Terminal is assigned to the BC, and byte-oriented
Bus Terminals are given compact mapping (user data only)

11
The Bus Terminal is assigned to the BC, and byte-oriented
Bus Terminals are given complex mapping (with control

Compact
Compact evaluation of a byte-oriented Bus Terminal means that only the
user data is transmitted.
Example: a KL3xx2 has 2 input words, and a KL4xx2 has 2 output words.
Complex
Complex evaluation of a byte-oriented Bus Terminal means that the user
data and the control and status byte are transmitted.
Example: a KL3xx2 has 4 input words and 4 output words; the same
applies to a KL4xx2.
You will find further information in the documentation for the Bus
Terminals.
