8.5 The Programmers Model
There are 128, 8-bit registers within the camera, accessible by the user via the serial interface. They are grouped according to
function with each group occupying a 16-byte page of the location address space. There may be up to eight such groups,
although this scheme is purely a conceptual feature and not related to the actual hardware implementation, The primary
categories are given below:
• Status Registers (Read Only).
• Setup registers with bit significant functions.
• Exposure parameters that influence output image brightness.
• System functions and analog test bit significant registers.
Any internal register that can be written to can also be read from. There are a number of read only registers that contain device
status information, (e.g. design revision details).
Names that end with H or L denote the most or least significant part of the internal register. Note that unused locations in the H
byte are packed with zeroes.
STMicroelectronics sensors that include a 2-wire serial interface are designed with a common address space. If a register
parameter is unused in a design, but has been allocated an address in the generic design model, the location is referred to as
reserved. If the user attempts to read from any of these reserved or unused locations a default byte will be read back. In
VV5301/VV6301 this data is 12H. A write instruction to a reserved (but unused) location is illegal and would not be successful as
the device would not allocate an internal register to the data word contained in the instruction.
A detailed description of each register follows. The address indexes are shown as decimal numbers in brackets [....] and are
expressed in decimal and hexadecimal respectively.
