Exposure control mode (M)
There are various modes available to control the exposure time and frame dura-
tion of the Bonito CL-400B/C. The exposure control is depending on some gen-
eral timing parameters which are specified in the following table:
Use parameter M to setup the exposure control mode. The bits of the parame-
ter value are divided into three different sized bit groups e, p and f. Each bit
group has a special function being independent of the other ones:
