(1) The status bits are purely informational. These bits are not required to know when the data is valid. The DVAL, LVAL and

FVAL signals are sufficient to know when to sample the image data.

INTE1/2 will be low when FOT is high, so the exposure during the small 0.43*reg73 overlap

(see formulas in 7.4.1), will not be visible in the INTE1/2 bits.

Pins H2 (TDIG1) and G2 (TDIG2) can be programmed to map the state of control channel bits

[0] (DVAL), [1] (LVAL), [2] (FVAL), [6] (INTE1) or [7] (INTE2) with registers 108 (T_dig1) and

109 (T_dig2).

DVAL, LVAL, FVAL

The first three bits of the control word must be used to identify valid data and the read-out

status.

Figure 42 shows the timing of the DVAL, LVAL and FVAL bits of the control channel with an

example of the read-out of a frame of 3 rows (default is 1088 rows). This example uses the

default mode of 16 outputs in 10-bit mode.
