; This pal serves as indicators logic, adi interrupts logic
; and future support for MC68040 buffers configuration (via IPL).
; RUN040 drives the run040 led when TIP is active (low).
; RUNDM drives the rundma led when AS is active (low).
; HLT drives the halt led according to the state of PST(0:3).
; H_NMI serves as a FF for the host generated level 7 interrupt.
; H_BRK_ is a simulated o.c. output for the ADI's host break, OE
; of which is driven by H_BRK.
