Data Type: Any.
USAGE: Writing any value to this register will cause the Delta_X, Delta_Y, and internal motion
registers to be cleared. Use this as a fast way to reset the motion counters to zero without
resetting the entire chip.
Data Type: Sixteen bit unsigned integer.
USAGE: Read these registers to determine the current frame period and to calculate the frame
rate. Units are clock cycles. The formula is
Frame Rate = Clock Frequency/Register value
To read from the registers, read Frame_Period_Upper first followed by Frame_Period Lower.
To set the frame rate manually, disable automatic frame rate mode via the Extended_Config
register and write the desired count value to the Frame_Period_Maximum_Bound registers.
The following table lists some Frame_Period values for popular frame rates with a 24MHz clock.
