Detecting Sandpoint 3  

Detecting Sandpoint 3  

Appendix B: Legacy Interrupt Support

Sandpoint 2 had an “interesting” interrupt architecture, mostly an attempt to funnel seven interrupts into the
four available MPMC interrupts with little logic support. SP3 solves this by using the “SPF100” logic in
conjunction with the serial interrupt EPIC device avaiable on Motorola MPMC cards.

However, for backward compatibility purposes, SP3 supports the SP 1/2 interrupt scheme. For more details
on the interconnections, refer to the SPX2TS (Sandpoint 2 Technical Summary), available on the Motorola
Website.

To enable Legacy-mode interrupt connections, set the ILEGACY switch OFF (SW2-3 to the left). Then
select one of the interrupt connections according to Table 23.

Note: This SP3 supports legacy mode in the manner SP2 should have; namely, supporting IDE interrupt
from the Winbond on INTC#/INTD# (SP3) instead of INTA#/INTB# (SP2); there’s not much point
emulating SP2 bugs.

Using the standard modes is highly encouraged, as nothing like this will be supported on future Sandpoint
platform or any other platform.
