Frame_Period_Max_Bound_Lower
Address: 0x19
Access: Read/Write
Reset Value: 0xE0
Frame_Period_Max_Bound_Upper
Address: 0x1A
Access: Read/Write
Reset Value: 0x2E
Data Type: 16-bit unsigned integer.
USAGE: This value sets the maximum frame period (the MINIMUM frame rate) which may be
selected by the automatic frame rate control, or sets the actual frame period when operating in
manual mode. Units are clock cycles. The formula is
Frame Rate = Clock Frequency / Register value
To read from the registers, read Upper first followed by Lower. To write to the registers, write
Lower first, followed by Upper. To set the frame rate manually, disable automatic frame rate
mode via the
Extended_Config
register and write the desired count value to these registers.
Writing to the Frame_Period_Max_Bound_Upper and Lower registers also activates any new values
in the following registers:
Frame_Period_Max_Bound_Upper and Lower
Frame_Period_Min_Bound_Upper and Lower
Shutter_Max_Bound_Upper and Lower
Any data written to these registers will be saved but will not take effect until the write to the
Frame_Period_Max_Bound_Upper and Lower is complete. After writing to this register, two
complete frame times are required to implement the new settings. Writing to any of the above
registers before the implementation is complete may put the chip into an undefined state
requiring a reset. 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.
The following table lists some Frame_Period values for popular frame rates (clock rate = 24MHz).
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.
