Table 20: 40 Bit Revolution Counter Register Map
Register Map, Overview
POS:
revolution counter (value is inverted if
LPP=1)
LMP:
polarity of the last magnet polarity
(1=positive, 0 = negative)
LPP:
polarity of last Wiegand pulse
(1=positive, 0 = negative)
CRC:
CRC for byte 0x0, bit 0 up to the most
significant bit of POS
INVALID: error information (position data changed
during read access, please discard the
data and read it again)
C3, C2, C1, C0:
Value of the Pins C3-C0, sampled during
the last wiegand pulse processing
