The Link drives a TX CMD byte with DATA[7:6] = 11h for a register read. DATA[5:0] of the ULPI TX command bye contain the register address. At T0, the Link will place the TX CMD on the data bus. At T2, the PHY will bring NXT high, signaling the Link it is ready to accept the data transfer. At T3, the PHY reads the TX CMD, determines it is a register read, and asserts DIR to gain control of the bus. The PHY will also de-assert NXT. At T4, the bus ownership has transferred back to the PHY and the FIGURE 6-4: ULPI EXTENDED REGISTER WRITE IN SYNCHRONOUS MODE FIGURE 6-5: ULPI REGISTER READ IN SYNCHRONOUS MODE DIR CLK DATA[7:0] STP NXT TXD CMD (extended reg write) Idle Reg Data[n] Idle ULPI Register Reg Data [n-1] Reg Data [n] T0 T1 T2 T3 T5 T4 T6 Extended address T7 DIR CLK DATA[7:0] STP NXT TXD CMD reg read Idle T0 Reg Data Turn around Turn around T1 T2 T3 T4 T5 T6 Idle |
