For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
Status register set
contents (on page C-1) and Enable and transition registers (on page C-20). The individual bits of this
register are defined in the following table.
Bit Value Description
B0 Not used Not applicable
B1 status.system5.NODE57 Bit B1 decimal value: 2
B2
status.system5.NODE58
Bit B2 decimal value: 4
B3 status.system5.NODE59 Bit B3 decimal value: 8
B4 status.system5.NODE60 Bit B4 decimal value: 16
B5 status.system5.NODE61 Bit B5 decimal value: 32
B6 status.system5.NODE62 Bit B6 decimal value: 64
B7 status.system5.NODE63 Bit B7 decimal value: 128
B8
status.system5.NODE64
Bit B8 decimal value: 256
B9-B15 Not used Not applicable
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.
