AMIS-720658: Contact Image Sensor
Data Sheet
Figures 4 and 5 show the initialization of the first sensor in relation to its subsequent cascaded sensors. The SIC selects the first sensor
to operate with 82 clock cycles of delay by connecting it to Vdd on the first sensor and to Ground for all of the subsequent sensors,
hence the first sensor will operate with 82 inactive pixels being clocked out before its first active pixel is clocked out.
