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
1.29000e+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
status.system3.EXTENSION_BIT
status.system3.EXT
B1
Bit B1 decimal value: 2
B5
Bit B5 decimal value: 32
Bit B7 decimal value: 128
Bit B8 decimal value: 256
B9
Bit B9 decimal value: 512
Bit B10 decimal value: 1,024
Bit B11 decimal value: 2,048
Bit B12 decimal value: 4,096
Bit B13 decimal value: 8,192
B14
Bit B14 decimal value: 16,384
As an example, to set bit B0 of the system summary 3 enable register, set
status.system3.enable = status.system3.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).
