status.system5.* (on page 9-207)
Sets the extension bit of the system2 enable register:
status.system2.enable = status.system2.EXT
TSP-Link system3 data structure register set.
To read condition, enable and event registers:
enablereg = status.system3.condition
enablereg = status.system3.enable
enablereg = status.system3.event
To write to enable register:
status.system3.enable = enablereg
Set enablereg to one of the following values:
0 Clears all bits.
To set EXT bit (B0)
1 or status.system3.EXTENSION_BIT
1 or status.system3.EXT
To set a node bit (Bn); n = 29 to 42.
status.system3.NODEn

In an expanded system (TSP- Link), this attribute is used to read or write to the
system3 node registers.

Reading a system3 node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system3 node register are
identified as follows:
B0 - EXT B4 - Node 32
B1 - Node 29 B5 - Node 33
B2 - Node 30 B6 - Node 34
B3 - Node 31 B7 - Node 35

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 31) are set.

Assigning a value to the status.system3.enable attribute sets the extension bit or a
node bit of the system3 node enable register.
