3. Serial data and description of functions
Detailed description
The serial interface data is loaded to the CXD2457R when D00 and D07 are 1. However, this
assumes that D32 to D39 CHKSUM is satisfied.

CTGRY: Mode control data
Detailed description
0: Power saving drive mode
1: High-speed drive mode
When FHIGH = 0, the clock input to CKI is immediately frequency divided by 1/3 and loaded
internally.
Mode switching timing
(5 clocks after the fall of HRI just before XSG is generated)
The high-speed phases of H1, H2, RG, XSHP, XSHD, XRS, ADCLK and other pulses are always
logically the same phase with respect to MCK.
0: DRAFT mode
1: FINE mode
In FINE mode, image data is taken by the normal Progressive Scan method.
In DRAFT mode, image data is taken by pulse elimination readout. This enables a frame rate
three times that during FINE mode. The mode is switched at the fall of HRI just before XSGA.
Note that the FRO output is also switched accordingly. (DRAFT mode: 264H, FINE mode: 792H)
0: Normal operation
1: Readout prohibited mode
In readout prohibited mode, a readout pulse is not added to V2A and V2B (V2A or V2B takes a
VH value). (V1, V2 and V3 are not modulated.)
The mode is normally switched at the fall of HRI just before the position where the readout pulse
is added.
