Description: Structure that is modified by an attached custom button panel for menu control of
camera. Do not modify this data.
6.3 Dynamic Configuration Structure (NVM_GLOBAL_CFG)
The dynamic configuration structure is the first structure member included in the global configuration.
It contains settings that control the camera’s ‘look and feel’. Typical settings include selection of video
and overlay palettes, AGC mode, reticle position, and additional features. The type definition of the
structure is located in
X
Appendix A
X
.
On boot - the structure is filled with data that is read back from a subset of the nonvolatile RAM on the
real time clock chip. This is the reason for the ‘NVM’ being a part of the member name. A complete
description of the contents of the nonvolatile RAM is located in
X
Appendix E
X
.
During program flow the software will use the settings located in the NVM_GLOBAL_CFG structure to
control behavior. The host can read these settings to determine the existing state and then use the
‘McbWriteDataMem’ routine to change a setting.
The paragraphs below will provide information about each of the data members (excluding reserved
areas) in this structure.
