NAME
     sa_spl - enable write bus error interrupts

SYNOPSIS
     void saspl()

DESCRIPTION
     Sa_spl sets the status register to enable write bus error
     interrupts detected by the CPU board hardware.  Because of
     the write buffers, bus errors on writes are detected after
     the store instruction that initiated the write; therefore,
     bus errors on writes are reported via interrupts.  When a
     fault has occurred, the standalone fault handling code dis-
     ables all interrupts and invokes either the standard fault
     handler or a user declared handler (see nofault(3spp)).  The
     fault handler should determine the cause of the fault and
     perform the appropriate action to terminate any pending
     interrupt requests.  Sa_spl can then be called to re-enable
     write bus error interrupts.  Sa_spl will clear a pending
     write bus error if one is present at the time it is called.
