; BKINT serves as a FF holding the request from the breakpoint logic.
; RSTS_ is a simulated o.c. driving the soft reset line of the quicc, while
; its OE is driven by RSTS
; RSTH_ is a simulated o.c. driving the hard reset line of the quicc, while
; its OE is driven by RSTH
; RSTS logically sums the conditions for soft reset: push-button, host
; soft reset and reset instruction (RSTO).
; RSTI logically sums the conditions for 040 reset: HARD reset
; (both push-buttons are depressed), P.B. SOFT reset, HOST hard and soft
; reset, P.U. reset and software watch-dog reset.
; RSTI is separated from RSTH_ in order of supporting soft reset as well.
