EPIC Serial Interrupt Mode AC
Timing Specifications
Table 17 provides the EPIC serial interrupt mode AC timing specifications for the
PC107A.
At recommended operating conditions (see Table 3 on page 12) with
LV

= 3.3
±
0.3V
Notes:
1. See the PC107A User’s 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 22 and Figure 23 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 PC107A 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 PC107A User’s Manual for a complete clocking description.
