In slave mode, the exposure and readout are controlled using the EXPOSURE,
STFRM_OUT, and STLN_OUT pins. When the slave mode is enabled, STFRM_OUT and
STLN_OUT become input pins.
The start and end of integration are controlled by EXPOSURE and STFRM_OUT pulses,
respectively. While a STFRM_OUT pulse is used to stop integration, it is also used to
enable the readout process.
After integration is stopped, the user provides STLN_OUT pulses to trigger row readout.
A full row of data is read out with each STLN_OUT pulse. The user must provide enough
time between successive STLN_OUT pulses to allow the complete readout of one row.
It is also important to provide additional STLN_OUT pulses to allow the sensors to read
the vertical blanking rows. It is recommended that the user program the vertical blank
register (R0x06) with a value of 4, and achieve additional vertical blanking between
frames by delaying the application of the STFRM_OUT pulse.
The elapsed time between the rising edge of STLN_OUT and the first valid pixel data is
calculated for context A by [horizontal blanking register (R0x05) + 4] clock cycles. For
context B, the time is (R0xCD + 4) clock cycles.
