Simultaneous Master Mode
ter mode: simultaneous master mode and sequential
master mode. One of these operation modes must be
selected via the two-wire serial interface. In simulta-
neous master mode the exposure period occurs during
readout. The frame synchronization waveforms are

No Blanking
With Vertical Blanking
N = number of rows in image
RT = row time
VB = vertical blanking rows (255 rows maximum); set in register 6
HB = horizontal blanking in SYSCLK cycles (255 maximum); set forth in register 6
There are two possible operation methods for mas-
Vertical blanking is nominally 1 SYSCLK and 0 row times, and may be increased by using register 6.
Vertical blanking is nominally 1 SYSCLK and 0 row times, and may be increased by using register 6.

shown in Figure 6 and Figure 7. This is the fastest
mode of operation since the exposure and readout are
happening in parallel rather than sequentially. Please
note that with this speed optimized timing the first row
readout is the last row of the previous frame that is still
in the row memory.
