status.operation.user.enable
status.operation.user.event
status.operation.user.ntr
status.operation.user.ptr
* = condition, enable, event, ntr or ptr
Attribute Operation user event register set.
Usage Reads condition, enable, event, NTR and PTR registers:
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 Clears all bits.
status.operation.user.BIT0 Sets user BIT0.
status.operation.user.BIT1 Sets user BIT1.
status.operation.user.BIT2 Sets user BIT2.
status.operation.user.BIT3 Sets user BIT3.
status.operation.user.BIT4 Sets user BIT4.
status.operation.user.BIT5 Sets user BIT5.
status.operation.user.BIT6 Sets user BIT6.
status.operation.user.BIT7 Sets user BIT.
status.operation.user.BIT8 Sets user BIT.
status.operation.user.BIT9 Sets user BIT.
status.operation.user.BIT10 Sets user BIT.
status.operation.user.BIT11 Sets user BIT.
status.operation.user.BIT12 Sets user BIT.
status.operation.user.BIT13 Sets user BIT.
status.operation.user.BIT14 Sets user BIT.
operreg can also be set to the decimal weight of the bit to be set. Examples:
To set user BIT0, set operreg to 1 (2
0
).
To set user BIT4, set operreg to 16 (2
4
).
To set user BIT11, set operreg to 2048 (2
11
).
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 Registers” in Appendix D.
Example Sets user BIT0 of the operation user enable register:
status.operation.user.enable = status.operation.user.BIT0
