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 status.system4.EXTENSION_BIT
status.system4.EXT
Bit B0 decimal value: 1
B1 status.system4.NODE43 Bit B1 decimal value: 2
B2 status.system4.NODE44 Bit B2 decimal value: 4
B3
status.system4.NODE45
Bit B3 decimal value: 8
B4 status.system4.NODE46 Bit B4 decimal value: 16
B5
status.system4.NODE47
Bit B5 decimal value: 32
B6 status.system4.NODE48 Bit B6 decimal value: 64
B7 status.system4.NODE49 Bit B7 decimal value: 128
B8
status.system4.NODE50
Bit B8 decimal value: 256
B9 status.system4.NODE51 Bit B9 decimal value: 512
B10
status.system4.NODE52
Bit B10 decimal value: 1,024
B11 status.system4.NODE53 Bit B11 decimal value: 2,048
B12 status.system4.NODE54 Bit B12 decimal value: 4,096
B13 status.system4.NODE55 Bit B13 decimal value: 8,192
B14
status.system4.NODE56
Bit B14 decimal value: 16,384
B15 Not used Not applicable
As an example, to set bit B0 of the system summary 4 enable register, set
status.system4.enable = status.system4.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).

of the system summary 4 enable
register.
