Notes:
1. All PCI signals are measured from GVDD_OVDD/2 of the rising edge of PCI_SYNC_IN to 0.4 × GVDD_OVDD of the
signal in question for 3.3-V PCI signaling levels. See Figure 12.
2. All memory and related interface input signal specifications are measured from the TTL level (0.8 or 2.0 V) of the
signal in question to the VM = 1.4 V of the rising edge of the memory bus clock. sys_logic_clk. 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. Input timings are measured at the pin.
4. tCLK is the time of one SDRAM_SYNC_IN clock cycle.
5. All mode select input signals specifications are measured from the TTL level (0.8 or 2.0 V) of the signal in question
to the VM = 1.4 V of the rising edge of the HRST_CPU/HRST_CTRL signal. See Figure 13.
6. The memory interface input setup and hold times are programmable to four possible combinations by programming
bits 5:4 of register offset <0x77> to select the desired input setup and hold times.
7. Tos represents a timing adjustment for SDRAM_SYNC_IN with respect to sys_logic_clk. Due to the internal delay
present on the SDRAM_SYNC_IN signal with respect to the sys_logic_clk inputs to the DLL, the resulting SDRAM
clocks become offset by the delay amount. The feedback trace length of SDRAM_SYNC_OUT to
SDRAM_SYNC_IN must be shortened to accommodate this range relative to the SDRAM clock output trace lengths
to maintain phase-alignment of the memory clocks with respect to sys_logic_clk. It is recommended that the length
of SDRAM_SYNC_OUT to SDRAM_SYNC_IN be shortened by 0.7 ns. This is because that is the midpoint of the
range of Tos and allows the impact from the range of Tos to be reduced. Additional analyses taking into account trace
lengths and SDRAM loading will need to be performed to optimize timing. For more details on trace measurements
and accommodating for the Tos problem, refer to the Motorola application note AN2164, MPC8245/MPC8241
