Programming the Exposure Time
In master mode, the exposure time is configured in two distinct methods (controlled by register seqmode3[6]):

Table 14. User Programmable Timer Settings
Note that the seqmode3[7] can also be used to sync the user signals in slave mode. The behavior is exactly the same.
Master Mode
In master mode the reset and exposure time is written in registers.
Ensure that the added value of the registers res_length and tint_timer always exceeds the number of lines that are read out. This is
because the sequencer samples a new image after integration is complete, without checking if image readout is finished. Enlarging
res_length to accommodate for this has no impact on image capture.

#lines: Obvious, changing signals that control integration time. They are always changed during ROT to avoid any image artefacts.
#clock cycles: Must be multiplied by (2**seqmode4[3:0]). When the counter expires, changes are put into effect immediately. Asserting
the configuration signal (seqmode3[7]) forces delaying signal updates until the next ROT.
