Data Sheet
Instruction 5: Connection Memory Extraction
Instruction 6: Channel 0 Extraction
Mask Store Control
First Data Transfer
Repeated Data Transfer
Note 1: Reading OR 2 is optional after mask store or redefinition, because the instruction is only activated by a not zero mask
Note 2: After the mask store operation (N2 N1 N0) is the sum of activated channels; after DR it is the sum of active channels;
Tn = 1 means activation of the function after mask store. After DR only Tn=1 can appear to flag a not zero mask writing.
Note 3: Reading of OR2 is mandatory after DR in order to step the data transfer; reading OR1 is also needed to scan in the
descending order of priority. Only relevant messages are considered, that means only messages with a signature different from
01. (P2 P1 P0) is the PCM bus on which the message in OR1 was found; Fn is a continuation bit which flags with a 1/0 level
more / no more extraction will be performed.
