status.system3.*
.condition
.enable
.event
Example
Sets the extension bit of the system3 enable register:
status.system3.enable = status.system3.EXT
status.system4.*
.condition
.enable
.event
Attribute
TSP-Link
TM
system4 data structure register set.
Usage
To read condition, enable and event registers:
enablereg = status.system4.condition
enablereg = status.system4.enable
enablereg = status.system4.event
To write to enable register:
status.system4.enable = enablereg
Set enablereg to one of the following values:
0 Clears all bits.
To set EXT bit (B0):
1 or status.system4.EXTENSION_BIT
- or -
1 or status.system4.EXT
To set a node bit (Bn); n = 43 to 56.
status.system4.NODEn
Remarks
In an expanded system (TSP-Link), this attribute is used to read or write to the
system4 node registers.
Reading a system4 node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system4 node register are
identified as follows:
B0-EXT bit
B4-Node 46
B8-Node 50
B12-Node 54
B1-Node43
B5-Node47
B9-Node51
B13-Node55
B2-Node44
B6-Node48
B10-Node52
B14-Node56
B3-Node45
B7-Node49
B11-Node53
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 45) are set.
Assigning a value to the status.system4.enable attribute sets the extension bit or a
node bit of the system4 node enable register.
