Details
These attributes are used to read or write to the operation status user registers. Reading a status
register returns a value. The binary equivalent of the value indicates which register bits are set. In the
binary equivalent, the least significant bit is bit B0, and the most significant bit is bit B15. For example,
if a value of 1.29000e+02 (which is 129) is read as the value of the condition register, the binary
equivalent is 0000 0000 1000 0001. This value indicates that bits B0 and B7 are set.

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
status.operation.user.BIT1
status.operation.user.BIT2
status.operation.user.BIT3
status.operation.user.BIT4
status.operation.user.BIT5
status.operation.user.BIT6
status.operation.user.BIT7
Bit B7 decimal value: 128
status.operation.user.BIT8
Bit B8 decimal value: 256
status.operation.user.BIT9
Bit B9 decimal value: 512
status.operation.user.BIT10
Bit B10 decimal value: 1,024
status.operation.user.BIT11
Bit B11 decimal value: 2,048
B12
status.operation.user.BIT12
Bit B12 decimal value: 4,096
status.operation.user.BIT13
Bit B13 decimal value: 8,192
status.operation.user.BIT14
Bit B14 decimal value: 16,384
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).
