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.

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.
