The Serial Interface port of the SL11R is used to pass control information to the camera and to communicate with serial EPROM1,
and EPROM2 (EPROM 1 is used to store camera default data). The Serial Port Control Register determines if the next operation
will be a write cycle to the camera or the EEPROM, or if the operation will be a read cycle of the EPROM. When an EPROM or
camera cycle is required the device must be selected in the Control Register, and an EEPROM address location must be written
to the Serial Interface Address Register. When a Read Cycle is selected, writing the Busy Bit begins the cycle, and when
completed, the valid returned data can be read in the Serial Interface Data Read Register.
The SL11R has a dedicated serial bus to support the camera and EPROM. On power up, an SL11R signal, AEEP, is driven high,
(AEEP connects to the Camera DSP device), the SL11R Camera serial bus is three-stated, which allows the Camera DSP to
read the camera default data directly from the EEPROM. (During this time the DSP drives the Serial Clock to the EEPROM and
the CCS select line to the SL11R, EEP1 is driven high from the SL11R). After a timed interval, the AEEP line is driven low and
the SL11R can now communicate to the camera via the Camera Serial Port.

When data is transmitted, setting the Busy bit in the Control Status Register initiates transmission.

When set = ’1’ capture even then odd field else when ’0’ capture even field only.
Start Capture When set = ’1’, clears to ’0’ when done.

Mode Setting:
When Set = ’1’, initiates a cycle to selected target. Cleared to ’0’ when the cycle has
completed. No new cycles are allowed until Busy bit = ’0’.
Command: 101 = Write, 110 = read
EEPROM or Camera Register address.
