EMIF Z group consists of:

AEA[22:3], AED[63:0], ACE[3:0], ABE[7:0], AARE/ASDCAS/ASADS/ASRE, AAWE/ASDWE/ASWE,

and AAOE/ASDRAS/ASOE, ASOE3, ASDCKE, and APDT.

EMIF high group consists of:

AHOLDA (when the corresponding HOLD input is high)

EMIF low group consists of:

ABUSREQ; AHOLDA (when the corresponding HOLD input is low)

Z group consists of:

HD[31:0] and the muxed EMAC output pins, MDCLK, MDIO, CLKX0, FSX0, DX0, CLKR0, FSR0,

TOUT0, TOUT1, VDAC/GP0[8], GP0[13, 11, 10, 7:0], HR/W, HDS2, HDS1, HCS, HCNTL1, HAS,

HCNTL0, HHWIL (16-bit HPI mode only), HRDY, HINT, VP1D[19:0], and VP2D[19:0].

If AEA[22:19], LENDIAN, and HD5 pins are actively driven, care must be taken to ensure no timing contention between parameters

6, 7, 14, 15, 16, and 17.

Boot and Device Configurations Inputs (during reset) include: AEA[22:19], LENDIAN, and HD5.
