As an example, to set bit B1 of the system summary 5 enable register, set
status.system5.enable = status.system5.NODE57
.
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 B1 and B4, set
enableRegister
to 18 (which is the sum of 2 +
16).

Example 1
enableRegister = status.system5.
status.system5.NODE60
status.system2.enable = enableRegister
Uses constants to set bits B1 and B4 of
the system summary 5 enable register.
Example 2
-- decimal 18 = binary 0000 0000 0001 0010
enableRegister = 18
status.system5.enable = enableRegister
Uses a decimal value to set bits B1 and
B4 of the system summary 5 enable
register.
