4.5.4 Absolute Linear Scale Reception Sequence
4-40
Final absolute data P
M
is calculated by the follow-
ing formula.
Note: This formula also applies for the reverse
direction mode (Pn000.0 = 1).
Note: When host controller receives the data of absolute linear scale, do not perform counter reset using the output of PCO
signal.
