*3 Only one bit among the BFM #25 b6 to b4 and b12 to b8 can be turned on. If two or more bits among them
are turned on, no operation is performed.
*4 When data is written into the BFMs #0, #1, #2, #3, #4, #5, #6 and #15, data is calculated inside the PGU during
the first positioning operation. To save this processing time (500 ms maximum).
