;*************************************************************************
; This pal is meant to fix the core-disable problem in the quicc.
; It contains a 6 bit synchronous counter, which starts counting after
; RESETH_ is asserted.
; During the first 64 clocks since RESETH_ is asserted, CONF2 is held at
; '1' to allow reset of the CORE. On the next clock CONF2 is driven low
; until RESETH_ is negated. After that CONF2 is tri-stated and held down
; by an external pull-down resistor.
