A. EMIF Z group consists of: AEA[22:3], AED[63:0], ACE[3:0], ABE[7:0], AARE/ASDCAS/ASADS/ASRE,
AAWE/ASDWE/ASWE, 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)
Low group consists of: XSP_CS, XSP_CLK/MDCLK, and XSP_DO/MDIO all of which apply only when PCI
EEPROM is enabled (with PCI_EN = 1 and MCBSP2_EN = 0). Otherwise, the XSP_CLK/MDCLK and
XSP_DO/MDIO pins are in the Z group. For more details on the PCI configuration pins, see the Device Configurations
section of this data sheet.
Z group consists of: HD[31:0]/AD[31:0] and the muxed EMAC output pins, XSP_CLK/MDCLK, XSP_DO/MDIO,
VP0D[2]/CLKX0, VP1D[2]/CLKX1, VP0D[3]/FSX0, VP1D[3]/FSX1, VP0D[4]/DX0, VP1D[4]/DX1, VP0D[8]/CLKR0,
VP1D[8]/CLKR1, VP0D[7]/FSR0, VP1D[7]/FSR1, TOUT0, TOUT1, VDAC/GP0[8]/PCI66, GP0[7:0], GP0[10]/PCBE3,
HR/W/PCBE2, HDS2/PCBE1, PCBE0, GP0[13]/PINTA, GP0[11]/PREQ, HDS1/PSERR, HCS/PPERR,
HCNTL1/PDEVSEL, HAS/PPAR, HCNTL0/PSTOP, HHWIL/PTRDY (16-bit HPI mode only), HRDY/PIRDY,
HINT/PFRAME, VP0D[19:9, 6,5,1,0], VP1D[19:9, 6,5,1,0], and VP2D[19:0].
B. If AEA[22:19], LENDIAN, PCIEEAI, and HD5/AD5 pins are actively driven, care must be taken to ensure no timing
contention between parameters 6, 7, 14, 15, 16, and 17.
C. Boot and Device Configurations Inputs (during reset) include: AEA[22:19], LENDIAN, PCIEEAI, and HD5/AD5.
The PCI_EN pin must be driven valid at all times and the user must not switch values throughout device operation.
