Frame_Period_Min_Bound_Lower
Access: Read/Write
Frame_Period_Min_Bound_Upper
Access: Read/Write
Data Type: 16-bit unsigned integer.
USAGE: This value sets the minimum frame period (the MAXIMUM frame rate) which may be selected by the automatic
frame rate control. Units are clock cycles. The formula is
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 0x0D3E; 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 t Frame_Period_Min_Bound + Shutter_Max_Bound.
