OR2: See Note 3

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.
