SRAM is internal control bit which is high means the OV7620 enter external RAM status. This is

programmed by SCCB (register 27) or power-on read-in. When SRAM=1, OV7620 all data bus

will be tri-stated and ready to send the data. Micro-controller will send a initial signal to FPGA to

reset all RAM Address block, after that, there are two method to get one frame data frame

OV7620:

1. Micro-controller send a initial pulse to OV7620 AGCEN input pin

2. Micro-controller send a SCCB command to program OV7620 send Single frame data

The OV7620 output signal VS is the ACK signal from sensor, when VS is high means OV7620

is in ready status, when VS is low, means OV7620 will send one frame data.
