EXTENDPRELL param [; TEXT]
Duration of additional debounce time in 1/60 of a second. Value range from param:
00 to 3F hex. Active, when the IO-Attribute in the keyword KEY is iBit 7=0.
SPEZBREAK param [; TEXT]
Special break code. Value range from param: 00 to 7F hex. If bit 6 is in attribute 1
or attribute 2 =0 (when KEY is the keyword), the special break code is sent instead
of the normal break code.

param1 (Matrix no.) specifies the position in the key matrix or the number of the
input switch. The input switches are not wired and cannot therefore be used by the
user. The first param1 digit is the X matrix node of the key, the second param1
digit is the Y matrix node of the key (see Figure 3.3).
param2/5 (AT code1 / AT code2) specifies the running number of the key (see
Figure 3.2). For normal keys, the value range is from param2/5: 00 to 7F hex. If no
key code is to be sent, for example if the key is to be assigned parameters as a
shift key or a direct key, param2/5 is set to FF hex.
param3/6 (Attribute1 / Attribute2) controls the key function individually. This
means that you can, for example, specify whether the auto-repeat key is to be
executed. For individual functions, see the following table:
The function is active when the corresponding bit is set.
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

param4 (IO Attribute) controls the key function individually. This means that you
can, for example, specify whether the key switches to the second level
(param4=7F hex). Port functions cannot be used by the user; this means that Bit 0
to Bit 5 must always be =1. For individual functions, see the following table:
The function is active when the corresponding bit is set.
