expose_time_count - adds
additional time in µs for exposure after a complete pattern is
loaded(1)

(1) When a trigger occurs, the Loader
sends the pattern buffer to the DMD and performs a reset to display the pattern.
Expose time is wait time added after the reset is complete before the Loader
waits for the next trigger. Expose time is measured in row cycle counts:
For DLP9000X and
DLP9000XUV DMDs, row cycles are 20 dclk cycles long at 400 MHz or 480
MHz (50 ns or 41.67 ns).
For DLP65000 DMDs, row
cycles are 32 dclk cycles long at 400 MHz (80 ns).
For example, with the default Load Interval of 400 us, no change is
seen in the pattern load frequency until the total of load time plus reset time
plus expose time exceeds an integer multiple of 400 us. Therefore, the effective
step size is the APPS_LOAD_TRIG_INTERVAL - 0x0038.
