The programmable analog offset stage corrects for analog offset that might be present in
the analog signal. The user would need to program register 0x62 appropriately to enable
the analog offset correction.
The lower eight bits (bit[7:0]) determines the absolute value of the analog offset to be
corrected and bit[8] determines the sign of the correction. When bit[8] is “1”, the sign of
the correction is negative and vice versa. The analog value of the correction relative to
the analog gain stage can be determined from the following formula:
By setting bit 14 of Reg0x20, the readout order of the columns will be reversed, as shown
in Figure 11.
By setting bits 15 of Reg0x20 the readout order of the rows will be reversed, as shown in
Figure 12.

By setting bit 3 of Reg0x20, only half of the columns set will be read out. An example is
shown in Figure 13. Only columns with bit 1 equal to “0” will be read out (xxxxxxx0x).
The row skip works in the same way and will only read out rows with bit 1 equal to “0.”
Row skip mode is enabled by setting bit 4 of Reg0x20. For both row and column skips, the
number of rows or columns read out will be half of what is set in Reg0x03 or Reg0x04,
respectively.
