May need 5V tolerant protection at system level (DDC_SCL,
DDC_SDA).
The TFT_PRSNT strap determines the power-on reset (POR) state of
PMR[23].
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]).
Is 5V tolerant (ACK#, AFD#/DSTRB#, BUSY/WAIT#, ERR#, INIT#,
PD[7:0], PE, SLCT, SLIN#/ASTRB#, STB#/WRITE#, ONCTL#,
PWRCNT[2:1]).
The LPC_ROM strap determines the power-on reset (POR) state of
PMR[14] and PMR[22].
