Comments
The following bits are constantly updated, i.e. they are updated immediately after the respective event oc-
curs:
Reading gate state
• Further results in the buffer
• Buffer overflow
• Waiting for acknowledgment
All other flags refer to the currently output decoding result.
If the input data is reset to the initial value (see chapter 8.8.3 "Module 30 – Data formatting"), the following
bits are deleted:
• New result
• Result state
All others remain unchanged.
Data reset behavior
Upon data reset (see chapter 8.7.1 "Module 10 – Activations") the input data is deleted, except for the
reading gate status and the two toggle bits.
