Protect depositor and be set to 0, logical device release iic bus.
Wherein the second son protection depositor is used for showing that system is the most taking iic bus, prevents
System and logical device take iic bus simultaneously, cause iic bus conflict.System is grasped by iic bus
When making to access optical module internal register, first read total value protecting depositor, protect depositor when always
When the value of B is 1, shows that optical module iic bus is currently in use, do not allow system to be grasped by iic bus
Make to access optical module internal register；If in now system has initiated iic bus operational access optical module
Portion's register command, then report IIC BUSY error informing system；When the value of total protection depositor is 0
Time, showing that the optical module iic bus free time can use, then system can be visited normal through iic bus operation
Ask optical module internal register.Therefore, when system uses iic bus operation optical module internal register,
First the value of the second son protection depositor is set to 1, shows that system is occupying optical module iic bus, so
Rear system performs iic bus operation optical module internal register, treats that the operation of system iic bus is finished
After, the value of the second son protection depositor being put back into again is 0, system release iic bus.
