status.system5.*
.condition
.enable
.event
Remarks
In an expanded system (TSP-Link), this attribute is used to read or write to the
system5 node registers.
Reading a system5 node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system5 node register are
identified as follows:
Bit B0 - EXT
bit
Bit B4 - Node
60
Bit B8 - Node 64
Bit B1 - Node
57
Bit B5 - Node
61
Bits B9 through B15 - Not used
Bit B2 - Node
58
Bit B6 - Node
62
Bit B3 - Node
59
Bit B7 - Node
63
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 59) are
set.
Assigning a value to the status.system5.enable attribute sets the extension bit or a
node bit of the system5 node enable register.

status.system.* (on page 13-280)
status.system2.* (on page 13-281)
status.system3.* (on page 13-282)
status.system4.* (on page 13-284)
Example
Sets the extension bit of the system5 enable register:
status.system5.enable = status.system5.EXT
timer functions
Use the functions in this group to control the timer. The timer can be used to
measure the time it takes to perform various operations. Use the timer.reset()
(on page 13-287) function at the beginning of an operation to reset the timer to
zero, and then use the timer.measure.t() (on page 13-286) at the end of the
operation to measure the elapsed time.
timer.measure.t()
Function
Measures the elapsed time since the timer was last reset.
Usage
time = timer.measure.t()
time: Returns the elapsed time in seconds. (1 s resolution).
