B15 Not used Not applicable
As an example, to set bit B0 of the system summary status enable register, set
status.system.enable = status.system.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).

Example 1
enableRegister = status.system.
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.
