Related Parameters D, E, F, J, N, and S
Three sub-fields are available to control the exposure time and frame duration
of the Bonito CL-400B/C:
• Exposure timing mode
• PIV mode
• Exposure feature mode
All of these sub-fields are controlled by the parameter M, each of them working
independently from the other sub-fields. The sub-fields within the parameter M
are represented by differently sized bit groups.
To set a sub-field to a certain value, modify the associated bit group by allocat-
ing
M to the appropriate hexadecimal number.
