status.system.*
.condition
.enable
.event
Attribute
TSP-Link system data structure register set.
Usage
To read condition, enable and event registers:
enablereg = status.system.condition
enablereg = status.system.enable
enablereg = status.system.event
To write to enable register:
status.system.enable = enablereg
Set enablereg to one of the following values:
0
Clears all bits.
To set EXT bit (B0):
1
or
status.system.EXTENSION_BIT
- or -
1
or
status.system.EXT
To set a node bit (Bn); n = 1 to 14.
status.system.NODEn
Remarks
In an expanded system (TSP- Link), this attribute is used to read or write to the
system node registers.
Reading a system node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system node register are
identified as follows:
B0 - EXT bit
B4 - Node 4
B8 - Node 8
B12 - Node 12
B1 - Node 1
B5 - Node 5
B9 - Node 9
B13 - Node 13
B2 - Node 2
B6 - Node 6
B10 - Node 10
B14 - Node 14
B3 - Node 3
B7 - Node 7
B11 - Node 11
B15 - Not used
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 3) are set.
Assigning a value to the status.system.enable attribute sets the extension bit or a
node bit of the system node enable register.
