status.operation.user.event
status.operation.user.ntr
status.operation.user.ptr
* = condition, enable, event, ntr or ptr
Attribute Operation user event register set.
Reads condition, enable, event, NTR and PTR registers:
Usage
operreg = status.operation.user.condition
operreg = status.operation.user.enable
operreg = status.operation.user.event
operreg = status.operation.user.ntr
operreg = status.operation.user.ptr
Writes to condition, enable, NTR and PTR registers:
status.operation.user.condition = operreg
status.operation.user.enable = operreg
status.operation.user.ntr = operreg
status.operation.user.ptr = operreg
Set operreg to one of the following values:
0
status.operation.user.BIT0
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
status.operation.user.BIT8
status.operation.user.BIT9
status.operation.user.BIT10
status.operation.user.BIT11
status.operation.user.BIT12
status.operation.user.BIT13
status.operation.user.BIT14
operreg
To set user BIT0, set
To set user BIT4, set
To set user BIT11, set
To set more than one bit of the register, set operreg to the sum of their decimal weights.
For example, to set BIT0 and BIT4, set operreg to 17 (1 + 16).
Remarks • This attribute is used to read or write to the operation user registers.
• Bits of the user event register are set by setting the corresponding bits of the user enable
register and the user condition register. For example, the following code will set B1 (Bit 1)
of the user event register:
• status.operation.user.enable = 2
• status.operation.user.condition = 2
• Reading a status register returns a value. The binary equivalent of the returned value
indicates which register bits are set. The least significant bit of the binary number is bit 0,
and the most significant bit is bit 15.
• For example, assume value 17 is returned for the enable register. The binary equivalent is
0000000000010001. This value indicates that BIT0 and BIT4 are set.
Details See "Operation Event
Example Sets user BIT0 of the operation user enable register:
status.operation.user.enable = status.operation.user.BIT0
2600S-901-01 Rev. C / January 2008
can also be set to the decimal weight of the bit to be set. Examples:
to 1 (2
operreg
to 16 (2

to 2048 (2
