Further, SPL can be used during this mode to specify the SUB output at the optional vertical period during the
low-speed shutter period.
In the case below, SUB is output based on SHR at the SPL vertical period out of (SVR + 1) vertical periods.
Incidentally, SPL is counted as "000h", "001h", "002h" and so on in conformance with SVR. At this time even if
SPL > SVR is set, operation conforms to the state when SPL = SVR.
Using this function it is possible to achieve smooth exposure time transitions when changing from low-speed
shutter to high-speed shutter or vice versa.

Concretely, when specifying high-speed shutter, SVR is set to "000h". (See the figure.) During low-speed
shutter, or in other words when SVR is set to "001h" or higher, the serial interface data is not loaded until this
period is finished.
The vertical period indicated here corresponds to one field in each drive mode. In addition, the number of
horizontal periods applied to SHR can be considered as (number of SUB pulses
1).
