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.

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).
