Process image
The KL2535 and KL2545 appear in the complex process image with at least 6 bytes of input and 6 bytes of
output data. These are organized as follows:
Byte offset (without word
alignment)
Byte offset (with word align-
ment*)

DataOUT n: Output word of channel n
Note
Process image
It is not possible for the KL2535 or KL2545 to operate without control bytes, since the con-
trol bytes are required to enable the channels. Even if you adjust your bus coupler to the
compact process image, the KL2535 and KL2545 will still be represented with their control
bytes!
