Time after which to access the GSSR register, by force, if the software/firmware semaphore is still unavailable.
Time after which to access the EEPROM, by force, if GSSR.EEP_SM still not available.
Time after which to access PHY 0, by force, if GSSR.PHY_SM0 still not available.
Time after which to access PHY 1, by force, if GSSR.PHY_SM1 still not available.
Time after which to access the MAC CSR mechanism, by force, if GSSR.MAC_CSR_SM is still not available.

In a similar way, the SW_FLASH_SM is used to synchronize between the two software device drivers on
the Flash resource to make sure both drivers are not accessing the Flash at the same time. A software
device driver that wants to access the Flash, first checks the state of the SW_FLASH_SM bit, and if set,
does not access the Flash (used by the other software device). If it is cleared, the software device
driver sets the semaphore and then accesses the Flash. Once the software device driver completes all
Flash accesses, it releases the semaphore and enables the other software device driver to access the
Flash.
