WAIT
; G0 pin configured Hi-Z
; Ext interrupt polarity: falling edge
; Set the GIE bit
; Enable the external interrupt
; Wait for external interrupt
; The interrupt causes a
; branch to address 0FF
; The VIS causes a branch to
; interrupt vector table
; Vector table (within 256 byte
; of VIS inst.) containing the ext
; interrupt service routine
; Interrupt Service Routine
; Reset ext interrupt pend. bit
; Return, set the GIE bit
