Notes:
1. All PCI signals are measured from GVDD/2 of the rising edge of PCI_SYNC_IN to 0.285 × OVDD or 0.615 × OVDD of the
signal in question for 3.3 V PCI signaling levels. See Figure 12.
2. All memory and related interface output signal specifications are specified from the VM = 1.4 V of the rising edge of the
memory bus clock, sys_logic_clk to the TTL level (0.8 or 2.0 V) of the signal in question. sys_logic_clk is the same as
PCI_SYNC_IN in 1:1 mode, but is twice the frequency in 2:1 mode (processor/memory bus clock rising edges occur on every
rising and falling edge of PCI_SYNC_IN). See Figure 11.
3. PCI bused signals are composed of the following signals: LOCK, IRDY, C/BE[3:0], PAR, TRDY, FRAME, STOP, DEVSEL,
PERR, SERR, AD[31:0], REQ[4:0], GNT[4:0], IDSEL, and INTA.
4. To meet minimum output hold specifications relative to PCI_SYNC_IN for both 33- and 66-MHz PCI systems, the MPC8245
has a programmable output hold delay for PCI signals (the PCI_SYNC_IN to output valid timing is also affected). The initial
value of the output hold delay is determined by the values on the MCP and CKE reset configuration signals; the values on
these two signals are inverted and stored as the initial settings of PCI_HOLD_DEL = PMCR2[5, 4] (power management
configuration register 2 <0x72>), respectively. Since MCP and CKE have internal pull-up resistors, the default value of
PCI_HOLD_DEL after reset is 0b00. Further output hold delay values are available by programming the PCI_HOLD_DEL
value of the PMCR2 configuration register. Figure 15 shows the PCI_HOLD_DEL effect on output valid and hold times.
