The constant 113 in the formulas in Table 3 is the constant value in default mode, when
8 dark columns are read out through Reg0x30. The constant follows the dark columns
read out as shown in Table 4.
Sensor timing is shown above in terms of pixel clock and master clock cycles (please
refer to Figure 7). The recommended master clock frequency is 27 MHz.
The vertical blanking and total frame time equations assume that the number of integra-
tion rows (bits 11 through 0 of Reg0x09) is less than the number of active plus blanking
rows (Reg0x03 + 1 + Reg0x06 + 1). If this is not the case, the number of integration rows
must be used instead to determine the frame time, as shown in Table 5.
