VV5410 & VV6410
7.
The previous section, Exposure Control, introduced the concept of a “timed parameter”, that is information that is written via the
serial interface but will not be used immediately by the sensor, rather there will be a delay before the information is passed to the
internal registers (referred to as the working registers) from the serial interface registers (referred to as the shadow registers). It is
the contents of the working registers that will determine sensor behaviour.
The architecture of VV5410/6410 requires that many of the programmable registers are handled in such a manner. This section
will identify all these registers, describe what they are all used for and then go on to explain when they are all updated.
7.1
The timed parameters are split into 6 categories as follows:
There is a “pending” flag for each of the above categories. These flags are stored in Status0 Register[2]. If one of the flags is high
this indicates that the working register/s controlled by that flag have yet to be updated from the according shadow register/s. This
feedback information could be useful if a user is, for example, attempting to write an exposure controller. The status of the
pending flags allows accurate timing of the serial interface communications.
7.1.1
The fine exposure category simply comprises registers[32,33].
7.1.2
The coarse exposure category simply comprises registers[34,35].
7.1.3
The clock division category simply comprises register[37].
7.1.4
The gain category simply comprises register[36].
7.1.5
The pan parameter category comprises the following registers:
7.1.6
The tilt parameter category comprises the following registers:
