Function
Reading can be shortened if BCDs are not required.

(1010

)for”ABORT” is transmitted
after a BCD has been read. The reading stops with the identification of ”ABORT”.
•
In the case of the abort via a value digit, the least significant bit (LSB) is to be assigned with
”ABORT”, because the reading sequence stops at the least significant bit.
•
In the handshake mode, ”CANCEL” should be identified at the beginning of the data
transmission (see also the following chapter).
