Example 1
operationRegister = status.operation.USER +
status.operation.PROG
status.operation.enable = operationRegister
Sets the USER and PROG bits of the
operation status enable register using
constants.
Example 2
-- decimal 20480 = binary 0101 0000 0000 0000
operationRegister = 20480
status.operation.enable = operationRegister
Sets the USER and PROG bits of the
operation status enable register using a
decimal value.

Operation Status Registers (on page E-9)
status.operation.calibrating.*
This attribute contains the operation status calibration summary register set.
Type TSP-Link accessible Affected by Where saved Default value
Attribute - - - - - - - -

Usage
operationRegister = status.operation.calibrating.condition
operationRegister = status.operation.calibrating.enable
operationRegister = status.operation.calibrating.event
operationRegister = status.operation.calibrating.ntr
operationRegister = status.operation.calibrating.ptr
status.operation.calibrating.enable = operationRegister
status.operation.calibrating.ntr = operationRegister
status.operation.calibrating.ptr = operationRegister
operationRegister
The status of the operation calibrating event register; a zero (0) indicates no bits set
(also send 0 to clear all bits); the only valid value other than 0 is 2
