Sets the extension bit of the system enable register:
status.system.enable = status.system.EXT
TSP-Link system2 data structure register set.
Reads condition, enable and event registers:
enablereg = status.system2.condition
enablereg = status.system2.enable
enablereg = status.system2.event
Writes to enable register:
status.system2.enable = enablereg
Set enablereg to one of the following values:
0 Clears all bits.
To set EXT bit (B0):
1 or status.system2.EXTENSION_BIT
- or -
1 or status.system2.EXT
To set node bit (Bn); n = 15 to 28.
status.system2.NODEn

In an expanded system (TSP- Link), this attribute is used to read or write to the
system2 node registers.

Reading a system2 node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system2 node register are
identified as follows:
B0 - EXT bit B4 - Node 18
B1 - Node 15 B5 - Node 19
B2 - Node 16 B6 - Node 20
B3 - Node 17 B7 - Node 21

For example, assume value 9 is returned for the enable register. The binary
equivalent is 0000000000001001. This value indicates that bit 0 (EXT) and bit 3
(Node 17) are set.

Assigning a value to the status.system2.enable attribute sets the extension bit or a
node bit of the system2 node enable register.
