Example 1
enableRegister = status.system.NODE11 +
status.system.NODE14
status.system.enable = enableRegister
Uses constants to set bits B11 and B14
of the system summary enable register.
Example 2
-- decimal 18432 = binary 0100 1000 0000 0000
enableRegister = 18432
status.system.enable = enableRegister
Uses a decimal value to set bits B11 and
B14 of the system summary enable
register.

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 status of the system summary 2 register; a zero (0) indicates no bits set; other
values indicate various bit settings
