1.4.3.5 EPIC Serial Interrupt Mode AC Timing Specications
Table 15 provides the EPIC serial interrupt mode AC timing specications for the MPC107.
Notes:
1
See the MPC107 Users Manual for a description of the EPIC Interrupt Control Register (EICR)
describing S_CLK frequency programming.
2
S_RST, S_FRAME, and S_INT shown in Figure 16 and Figure 17 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 MPC107 Users 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 MPC107 Users
Manual for a complete clocking description.
