BIT FIELD
0: Flash should be enabled for one frame only.
1: Flash should be enabled every frame.
Enables LED flash. When set, the FLASH_STROBE goes on prior
to the start of a frame reset. When disabled, the FLASH_STROBE
remains HIGH until readout of the current frame completes.
Length of FLASH_STROBE pulse when Xenon flash is enabled.
The value specifies the length in 1,024 master clock cycle
increments.
Total gain = (Bit 9 + 1) x (Bit 10 + 1) (Bit 11 + 1) x analog gain
(each bit gives 2x gain).
Analog gain = (Bit 8 + 1) x (Bit 7 + 1) x initial gain (each bit gives
2x gain).
Initial gain = bits (6:0) x 0.03125.
Total gain = (Bit 9 + 1) x (Bit 10 + 1) (Bit 11 + 1) x analog gain
(each bit gives 2x gain).
Analog gain = (Bit 8 + 1) x (Bit 7 + 1) x initial gain (each bit gives
2x gain).
Initial gain = bits (6:0) x 0.03125.
Total gain = (Bit 9 + 1) x (Bit 10 + 1) x (Bit 11 + 1) x analog gain
(each bit gives 2x gain).
Analog gain = (Bit 8 + 1) x (Bit 7 + 1) x initial gain (each bit gives
2x gain).
Initial gain = bits (6:0) x 0.03125.
Total gain = (Bit 9 + 1) x (Bit 10 + 1) x (Bit 11 + 1) x analog gain
(each bit gives 2x gain).
Analog gain = (Bit 8 + 1) x (Bit 7 + 1) x initial gain (each bit gives
2x gain).
Initial gain = bits (6:0) x 0.03125.
This register can be used to set all four gains at once. When
read, it returns the value stored in Reg0x2B.
Setting this bit causes the sensor to abandon the current frame
and start resetting the first row. Same physical register as
Reg0x00D, bit 1.
