STANDBY Restricted Location
FRAME _VALID
1. Asserting STANDBY during the valid frame readout time (FRAME_VALID is HIGH)
2. Asserting STANDBY at the end of valid frame readout (falling edge of FRAME_VALID)
STANDBY cannot be asserted at any time. If STANDBY is asserted during a specific
window within the vertical blanking period, the MT9V032 may enter a permanent
standby state. This window (that is, dead zone) occurs prior to the beginning of the new
frame readout. The permanent standby state is identified by the absence of the
FRAME_VALID signal on frame readouts. Issuing a hardware reset (RESET# set to LOW
state) will return the image sensor to default startup conditions.
This dead zone can be avoided by:
When STANDBY is asserted during the vertical blanking period (FRAME_VALID is LOW),
the STANDBY signal must not change state between [Vertical Blanking Register (R0x06) -
5] row-times and [Vertical Blanking Register + 5] row-times after the falling edge of
FRAME_VALID.
and maintaining STANDBY assertion for a minimum of one frame period.
and maintaining STANDBY assertion for a minimum of [5 + R0x06] row-times.
