Example 1
enableRegister = status.system4.
status.system4.NODE56
status.system2.enable = enableRegister Uses constants to set bit B11 and bit B14
of the system summary 4 enable
register.
Example 2
-- decimal 18432 = binary 0100 1000 0000 0000
enableRegister = 18432
status.system4.enable = enableRegister Uses a decimal value to set bit B11 and
bit B14 of the system summary 4 enable
register.
