These C64x
devices have two EMIFs (EMIFA and EMIFB). All EMIFA signals are prefixed by an “A” and all EMIFB signals are prefixed by a
“B”. Throughout the rest of this document, in generic EMIF areas of discussion, the prefix “A” or “B” may be omitted [e.g., ECLKIN, ECLKOUT1,
and ECLKOUT2].
EMIF Z group consists of:
AEA[22:3], BEA[20:1], AED[63:0], BED[15:0], CE[3:0], ABE[7:0], BBE[1:0], ARE/SDCAS/SADS/SRE,
AWE/SDWE/SWE, and AOE/SDRAS/SOE, SOE3, ASDCKE, and PDT.
EMIF high group consists of: AHOLDA and BHOLDA (when the corresponding HOLD input is high)
EMIF low group consists of:
ABUSREQ and BBUSREQ; AHOLDA and BHOLDA (when the corresponding HOLD input is low)
Low group consists of:
XSP_CS, CLKX2/XSP_CLK, and DX2/XSP_DO; all of which apply only when PCI EEPROM (BEA13)
is enabled (with PCI_EN = 1 and MCBSP2_EN = 0). Otherwise, the CLKX2/XSP_CLK and DX2/XSP_DO
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], CLKX0, CLKX1/URADDR4, CLKX2/XSP_CLK, FSX0, FSX1/UXADDR3, FSX2, DX0,
DX1/UXADDR4, DX2/XSP_DO, CLKR0, CLKR1/URADDR2, CLKR2, FSR0, FSR1/UXADDR2, FSR2,
TOUT0, TOUT1, TOUT2, GP[8:0], GP10/PCBE3, HR/W/PCBE2, HDS2/PCBE1, PCBE0, GP13/PINTA,
GP11/PREQ, HDS1/PSERR, HCS/PPERR, HCNTL1/PDEVSEL, HAS/PPAR, HCNTL0/PSTOP,
HHWIL/PTRDY (16-bit HPI mode only), HRDY/PIRDY, HINT/PFRAME, UXDATA[7:0], UXSOC, UXCLAV,
and URCLAV.
§If BEA[20:13, 11, 7] 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: EMIFB address pins BEA[20:13, 11, 9:7] and HD5/AD5.
The PCI_EN pin
must
be driven valid at all times and the user
must not
switch values throughout device operation.
The MCBSP2_EN pin
must
be driven valid at all times and the user
can
switch values throughout device operation.
