Notes:
1. See the
MPC8245 Integrated Processor User’s Manual for a description of the PIC interrupt control register (ICR)
describing S_CLK frequency programming.
2. S_RST, S_FRAME, and S_INT shown in Figure 18 and Figure 19, depict timing relationships to
sys_logic_clk and
S_CLK and do not describe functional relationships between S_RST, S_FRAME, and S_INT. See the
MPC8245
Integrated Processor User’s Manual for a complete description of the functional relationships between these
signals.
3. The
sys_logic_clk waveform is the clocking signal of the internal peripheral logic from the output of the peripheral
logic PLL;
sys_logic_clk is the same as SDRAM_SYNC_IN when the SDRAM_SYNC_OUT to SDRAM_SYNC_IN
feedback loop is implemented and the DLL is locked. See the
MPC8245 Integrated Processor User’s Manual for a
complete clocking description.
