consists

of:

AHOLDA

(when

the

corresponding

input

high)

EMIF

low

group

consists

of:

ABUSREQ;

AHOLDA

(when

the

corresponding

input

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

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,

HRDY/PIRDY,

HINT/PFRAME, VP0D[19:9, 6,5,1,0], VP1D[19:9, 6,5,1,0], and VP2D[19:0].

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.

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.
