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.system4.EXTENSION_BIT
status.system4.EXT
Bit B0 decimal value: 1
B1 status.system4.NODE43 Bit B1 decimal value: 2
B2
status.system4.NODE44
Bit B2 decimal value: 4
B3 status.system4.NODE45 Bit B3 decimal value: 8
B4
status.system4.NODE46
Bit B4 decimal value: 16
B5 status.system4.NODE47 Bit B5 decimal value: 32
B6 status.system4.NODE48 Bit B6 decimal value: 64
B7
status.system4.NODE49
Bit B7 decimal value: 128
B8 status.system4.NODE50 Bit B8 decimal value: 256
B9
status.system4.NODE51
Bit B9 decimal value: 512
B10 status.system4.NODE52 Bit B10 decimal value: 1,024
B11
status.system4.NODE53
Bit B11 decimal value: 2,048
B12 status.system4.NODE54 Bit B12 decimal value: 4,096
B13 status.system4.NODE55 Bit B13 decimal value: 8,192
B14 status.system4.NODE56 Bit B14 decimal value: 16,384
B15 Not used Not applicable
As an example, to set bit B0 of the system summary 4 enable register, set
status.system4.enable =
status.system4.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).
