Usage
enableRegister = status.system2.condition
enableRegister = status.system2.enable
enableRegister = status.system2.event
enableRegister = status.system2.ntr
enableRegister = status.system2.ptr
status.system2.enable = enableRegister
status.system2.ntr = enableRegister
status.system2.ptr = enableRegister
enableRegister
The system summary 2 register's status. A zero (0) indicates no bits set; other
values indicate various bit settings
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.
