For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set contents (on
page E-1) and Enable and transition registers (on page E-19). The individual bits of this register are defined in
the following table.
Bit Value Description
B0
status.operation.user.BIT0
Bit B0 decimal value: 1
B1 status.operation.user.BIT1 Bit B1 decimal value: 2
B2
status.operation.user.BIT2
Bit B2 decimal value: 4
B3 status.operation.user.BIT3 Bit B3 decimal value: 8
B4
status.operation.user.BIT4
Bit B4 decimal value: 16
B5 status.operation.user.BIT5 Bit B5 decimal value: 32
B6 status.operation.user.BIT6 Bit B6 decimal value: 64
B7 status.operation.user.BIT7 Bit B7 decimal value: 128
B8 status.operation.user.BIT8 Bit B8 decimal value: 256
B9 status.operation.user.BIT9 Bit B9 decimal value: 512
B10 status.operation.user.BIT10 Bit B10 decimal value: 1,024
B11 status.operation.user.BIT11 Bit B11 decimal value: 2,048
B12 status.operation.user.BIT12 Bit B12 decimal value: 4,096
B13 status.operation.user.BIT13 Bit B13 decimal value: 8,192
B14
status.operation.user.BIT14
Bit B14 decimal value: 16,384
B15 Not used Not applicable
As an example, to set bit B0 of the operation status user enable register, set
status.operation.user.enable = status.operation.user.BIT0
.
In addition to the above constants,
operationRegister
can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set
operationRegister
to the sum of their decimal weights. For
example, to set bits B11 and B14, set
operationRegister
to 18,432 (which is the sum of 2,048 + 16,384).

Example 1
operationRegister = status.operation.user.BIT11 +
status.operation.user.BIT14
status.operation.user.enable = operationRegister
Uses constants to set bits B11 and B14
of the operation status user enable
register.
Example 2
-- 18432 = binary 0100 1000 0000 0000
operationRegister = 18432
status.operation.enable = operationRegister
Uses a decimal value to set bits B11 and
B14 of the operation status user enable
register.
