8 SPLD is deasserted for 22 SPCLK cycles, shifting the second PROM_DATA into the
network processor internal shift register.
9 SPLD is asserted for one SPCLK cycle, loading the second PROM_DATA into the
network processor PROM_RETURN_DATA register.

General System Interface Signal
Table 15 provides the signal for the Executive Processor reset power status and I/O clock.
The C-5 NP can be powered up with the XP either running or with the XP in reset mode
similar to the CPs. When the XP remains in reset mode, an external host can be used to
control the initialization of the C-5 NP.
