Activation of second punch interface
SPIF2 activates the second punch interface, i.e. the stroke is controlled via the second pair
of high-speed I/Os (see machine data MD26004 and MD26006).

Alternate interface
Machines that alternately use a second punching unit or a comparable medium can be
switched over to a second I/O pair.
The second I/O pair can be defined via the following machine data:
MD26004 $MC_NIBBLE_PUNCH_OUTMASK
MD26006 $MC_NIBBLE_PUNCH_INMASK
The interface is switched by command SPIF1 or SPIF2.
Full punching/nibbling functionality is available on both interfaces.

; The second stroke is initiated at the second high-
; speed output. The "Stroke active" signal is
; monitored at the second input.
; All further strokes are controlled with the first
