[HTSG control mode]

This mode controls the V1A/B and V3A/B ternary level outputs (readout pulse block) using D14 HTSG. When

control is applied, V pulse modulation does not occur during the readout period, and only normal V transfer is

performed.

Description of operation

Readout pulse (SG) normal operation

HTSG control mode

[EXP pulse]

The ID/EXP pin (Pin 4) output can be switched between 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. In draft mode, the transition point is midpoint value (1443ck) of the last SUB pulse falling edge

and each V1A/B and V3A/B ternary output falling edge. When there is no SUB pulse, the later ternary output

falling edge (1538ck) is used. In frame mode, the transition point is the last SUB pulse falling edge, and each

V1A/B and V3A/B ternary level output falling edge (1348ck). When there is no SUB pulse, the V pulse

modulation falling edge (1386ck) immediately after the ternary output is used. In addition, switching from the ID

pulse to the EXP pulse is performed at the ID reset timing (the ID transition point during the horizontal period of

each V1A/B and V3A/B ternary level output), and the EXP pulse is reset low at this point. See the EXP pulse

indicated in the explanatory diagrams under [Electronic shutter] for an image of operation.
