Table 83. D6D_SRC register description
DEN data-ready signal. It is set high when data output is related to the data coming from a
DEN active condition.⁽¹⁾
Interrupt active for change position portrait, landscape, face-up, face-down. Default value: 0
(0: change position not detected; 1: change position detected)
Z-axis high event (over threshold). Default value: 0
(0: event not detected; 1: event (over threshold) detected)
Z-axis low event (under threshold). Default value: 0
(0: event not detected; 1: event (under threshold) detected)
Y-axis high event (over threshold). Default value: 0
(0: event not detected; 1: event (over-threshold) detected)
Y-axis low event (under threshold). Default value: 0
(0: event not detected; 1: event (under threshold) detected)
X-axis high event (over threshold). Default value: 0
(0: event not detected; 1: event (over threshold) detected)
X-axis low event (under threshold). Default value: 0
(0: event not detected; 1: event (under threshold) detected)
1. The DEN data-ready signal can be latched or pulsed depending on the value of the dataready_pulsed bit of
the DRDY_PULSE_CFG (0Bh) register.
