Control data: D33 EXP [ID/EXP output switching]
The ID/EXP pin (Pin 4) output can be switched to the ID pulse or the EXP pulse using D33 EXP. The default
is the "ID" pulse. See the Timing Charts for the ID pulse.
The EXP pulse indicates the exposure time when it is high. Normally, high is indicated from the falling edge of
the last SUB to the falling edge of the next SG.
Note that the EXP pulse changes as follows when SUB does not rise.
Mode
Draft, 2-line addition 2, center scan 1
2-line addition 1, center scan 2
Monitoring, progressive scan, center scan 3, AF1, AF2
Last SG generation position
600, 750ck
1128, 1278ck
1100, 1250ck
EXP pulse rise point
804ck
1296ck
1322ck
Also, switching between ID and EXP is performed at the ID reset timing (the ID transition point during the
horizontal period with each V1A/B/C and V3A/B/C ternary output), and the pulse is also reset to low at this point.
See the explanatory diagrams under Electronic shutter for an image of ID/EXP pulse changes.
Control data: D34 and D35 PTOB [OBCLP waveform pattern]
This indicates the OBCLP waveform pattern. The default is "Normal".
Control data: D36 and D37 LDAD [ADCLK logic phase]
This indicates the ADCLK logic phase adjustment data. The default is "90
°
" relative to MCKO.

Control data: D38 and D39 STB [Standby]
The operating mode is switched as follows. However, the standby bits are loaded to the CXD3609R and control
is applied immediately at the rising edge of SEN.
See the Pin Status Table for the pin status in each mode.
