Table 8. Control Register 2 Description (Write to Address 06h to Set, Write to Address
07h to Clear)
Note 8:
To prevent a high-current state where the transceiver is both sourcing current to VBUSand sinking current from VBUS, the fol-
lowing logic is used to set bits 5, 6, and 7 of control register 2:
Setting vbus_drv clears vbus_dischrg and vbus_chrg
Setting vbus_dischrg clears vbus_drv and vbus_chrg, unless vbus_drv is set with the same command, in which case vbus_drv
clears the other bits
Setting vbus_chrg clears vbus_drv and vbus_dischrg, unless either of these bits are set with the same command, as shown in Table 9
