2.18 Strobe (STO Output) Function
2.18.1
Operation Outline
STO output is initiated by the serial data instruction, which includes the STO signal position and duration.
2.18.2
Operation Sequence
1.
Set data bit 6 = H at address 001010 for the STO (strobe) rising point instruction. See Note 1.
2.
Input a pulse to SLOAD and transfer the serial data.
3.
Set data bits 0
9 at address 000110 for the STO (strobe) rising point instruction. In this case, use the binary
code for data ST[9:0] starting from the HD rising edge (10 T), which is 2 H after the readout pulse. The
data range of ST is 0
n1
A
2, where A is the number of HD between VD
VD. See Note 3.
4.
Input a pulse to SLOAD and transfer the serial data.
5.
Set data bits 5
9 at address 000101 for the SWT duration instruction. In this case, use the binary code
for data SWT[9:5], starting from the STO rising edge (10 T). See Note 3.
6.
Input a pulse to SLOAD and transfer the serial data. Data is stored into the resistor at 1 H before the
readout operation. STO goes high at the point determined by the serial data instruction. STO goes low
when the duration of the STO high level extends beyond SWT in the interval between two HD pulses. See
Note 2.
NOTE:
1. The strobe function can be used in the normal mode as well as in the still mode. Then strobe
operation is useful for red-eye prevention.
2. Rise time and fall time of STO are 10 T.
3. Adjust the STO position and width so that STO goes low 2 HD before the readout operation.
