Shut_thr
Access: Read/Write
Data Type: 7 Bit number
USAGE: Threshold defines the Shutter value when lifted runaway happens.
Sensor will suspect lifted runaway happens and suppress motion if (Shutter > Shut_thr[7:1]*32).
Inverse_Revision_ID
Access: Read
Data Type: Inverse 8-Bit unsigned integer
USAGE: This value is the inverse of the Revision_ID. It can be used to test the SPI port.
Inverse_Product_ID
Access: Write Only
Data Type: Inverse 8-Bit unsigned integer
USAGE: This value is the inverse of the Product_ID. It can be used to test the SPI port.
Motion_Burst
Access: Read
Data Type: Various
USAGE: Read from this register to activate burst mode. The sensor will return the data in the Motion register, Delta_X_L,
Delta_Y_L, Delta_XY_H, Squal, Shutter_Upper, Shutter_Lower and Maximum_Pixel. Reading the first 3 bytes clears the
motion data. The read may be terminated anytime after Delta_X is read.
