Data Type: 16-bit unsigned integer.
USAGE: This value sets the minimum frame period (the MAXIMUM frame rate) that may be
selected by the automatic frame rate control. Units are clock cycles. The formula is
Frame Rate = Clock Rate / Register value
To read from the registers, read Upper first followed by Lower. To write to the registers, write
Lower first, followed by Upper, then execute a write to the Frame_Period_Max_Bound_Upper and
Lower registers. The minimum allowed write value is 0x7E0E; the maximum is 0xFFFF.
Reading this register will return the most recent value that was written to it. However, the value
will take effect only after a write to the Frame_Period_Max_Bound_Upper and Lower registers.
After writing to Frame_Period_Max_Bound_Upper, wait at least two frame times before writing to
Frame_Period_Min_Bound_Upper or Lower again. The “Busy” bit in the Extended_Config register
may be used in lieu of a timer to determine when it is safe to write. See the Extended_Config
register for more details.
In addition, the three bound registers must also follow this rule when set to non-default values:
Frame_Period_Max_Bound
≥
Frame_Period_Min_Bound + Shutter_Max_Bound.
