1.For Buffer Type definitions, refer to Table 9-10 "Buffer Types" on page 371.

2.Is 5V tolerant (ACK#, AFD#/DSTRB#, BUSY/WAIT#, ERR#, INIT#, PD[7:0], PE, SLCT, SLIN#/ASTRB#, STB#/WRITE#, ONCTL#, PWRCNT[2:1]).

3.The TFT_PRSNT strap determines the power-on reset (POR) state of PMR[23].

4.The LPC_ROM strap determines the power-on reset (POR) state of PMR[14] and PMR[22].

5.May need 5V tolerant protection at system level (DDC_SCL, DDC_SDA).

6.Is back-drive protected (MD[63:0], DPOS_PORT1, DNEG_PORT1, DPOS_PORT2, DNEG_PORT2, DPOS_PORT3, DNEG_PORT3, ACK#, AFD#/DSTRB#, BUSY/WAIT#, ERR#, INIT#, PD[7:0], PE, SLCT, SLIN#/ASTRB#, STB#/WRITE#, ONCTL#, PWRCNT[2:1]).
