1. Set up snapshot mode as normal (including any STROBE preferences).

The STROBE pulse must be enabled before use by setting R0x1E [bit 9] = 1. The STROBE
signal has two options for pulse length and may be selected using R0x1E [bit 10] as
shown in Table 10.
After the TRIGGER pulse has signaled a snapshot operation, each row of the imager
array is reset in sequence to clear out any accumulated signal. Once each row of the
imager is reset, the STROBE pulse is output from the imager with a length dependent
upon the characteristics described above. After the STROBE pulse goes low, the imager
waits 16 additional rows and then each row from the pixel array is read out. No STROBE
is generated unless the shutter width is greater than the output image height plus
vertical blanking.
R0x1E and R0x21
In addition to the standard snapshot mode, the MT9T031 has a global shutter release
mode which may be combined with a mechanical shutter to achieve simultaneous
exposure of all rows in the image.
Two global shutter modes are available: programmed exposure and bulb mode. In
programmed exposure mode, the exposure time is dictated by {R0x08, R0x09} (Shutter
Width). In bulb mode, the TRIGGER and GSHT_CTL pins are used to achieve an arbi-
trary exposure time.
To use programmed exposure mode:
remain HIGH for 18820 PIXCLKs.
exposure starts 1000 PIXCLKs after the falling edge of GSHT_CTL.
Unlike normal snapshot mode, R0x0B (Restart) may not be used to initiate the expo-
sure in global shutter modes.
