P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
This parameter applies to CLKMODE x1 when CLKIN is stable, and applies to CLKMODE x6, x12 when CLKIN and PLL are stable.
§
This parameter applies to CLKMODE x6, x12 only (it does not apply to CLKMODE x1). The RESET signal is not connected internally to the clock
PLL circuit. The PLL, however, may need up to 250
μ
s to stabilize following device power up or after PLL configuration has been changed. During
that time, RESET must be asserted to ensure proper device operation. See the
clock PLL
section for PLL lock times.
EMIFB address pins BEA[20:13, 11, 7] are the boot configuration pins during device reset.

E = 1/AECLKIN clock frequency in ns. C = 1/CLKIN clock frequency in ns. Select whichever value is larger for the

P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
E = the EMIF input clock (ECLKIN, CPU/4 clock, or CPU/6 clock) period in ns for EMIFA or EMIFB.
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,
