Details
In an expanded system (TSP-Link), these attributes are used to read or write to the system summary registers.
They are set using a constant or a numeric value, but are returned as a numeric value. The binary equivalent of
the value indicates which register bits are set. In the binary equivalent, the least significant bit is bit B0, and the
most significant bit is bit B15. For example, if a value of
1.02
(which is 129) is read as the value of the
condition register, the binary equivalent is 0000 0000 1000 0001. This value indicates that bit B0 and bit B7 are
set.

For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set contents (on
page E-1) and Enable and transition registers (on page E-19). The individual bits of this register are defined in
the following table.
Bit Value Description
B0 status.system.EXTENSION_BIT
status.system.EXT
Bit B0 decimal value: 1
B1
status.system.NODE1
Bit B1 decimal value: 2
B2 status.system.NODE2 Bit B2 decimal value: 4
B3
status.system.NODE3
Bit B3 decimal value: 8
B4 status.system.NODE4 Bit B4 decimal value: 16
B5
status.system.NODE5
Bit B5 decimal value: 32
B6
status.system.NODE6
Bit B6 decimal value: 64
B7 status.system.NODE7 Bit B7 decimal value: 128
B8
status.system.NODE8
Bit B8 decimal value: 256
B9 status.system.NODE9 Bit B9 decimal value: 512
B10 status.system.NODE10 Bit B10 decimal value: 1,024
B11
status.system.NODE11
Bit B11 decimal value: 2,048
B12 status.system.NODE12 Bit B12 decimal value: 4,096
B13 status.system.NODE13 Bit B13 decimal value: 8,192
B14 status.system.NODE14 Bit B14 decimal value: 16,384
B15 Not used Not applicable
As an example, to set bit B0 of the system summary status enable register, set
status.system.enable =
status.system.enable.EXT
.
In addition to the above constants,
enableRegister
can be set to the numeric equivalent of the bit to set. To
set more than one bit of the register, set
enableRegister
to the sum of their decimal weights. For example, to
set bits B11 and B14, set
enableRegister
to 18,432 (which is the sum of 2,048 + 16,384).
