0 ... 255: Word address of the parameter to be read/written.
0/1: Toggle bit to release new instructions from the application to the
module. If TGL_SM and TGL_MS have the same status, no new
instruction has been released yet. If the flags have different
statuses, a new instruction has been released and is currently
being processed.
0: Parameter data of A7...A0 is read
1: Parameter data is written to A7...A0
