Input Ports

Port Name	Required	Description	Comments
`data[]`	No	T-type flipflop: Toggle enable D-type flipflop: Data input	Input port `LPM_WIDTH` wide. If the `data[]` input is not used, at least one of the `aset`, `aclr`, `sset`, or `sclr` ports must be used. Unused data inputs default to `"GND"`.
`clock`	Yes	Positive-edge-triggered clock.
`enable`	No	Clock enable input.	If omitted, the default is `1`.
`sclr`	No	Synchronous clear input.	Clears the `q[]` outputs. If both the `sset` and `sclr` ports are used and asserted, the value of the `sclr` port is used.
`sset`	No	Synchronous set input.	Sets `q` outputs to the value specified by `LPM_SVALUE`, if that value is present, or sets the `q` outputs to all 1s. If both `sset` and `sclr` are used and both are asserted, `sclr` is used.
`sload`	No	Synchronous load input. Loads the flipflop with the value on the data input on the next active clock edge.	If omitted, the default is `0`. If `sload` is used, data must be used. For load operation, `sload` must be high (1) and enable must be high (1) or unconnected. The `sload` port is ignored when the `LPM_FFTYPE` parameter is set to `"DFF"`.
`aclr`	No	Asynchronous clear input.	Asynchronously clears the `q[]` outputs. If both `aset` and `aclr` are used and both are asserted, `aclr` is used.
`aset`	No	Asynchronous set input.	Sets `q[]` outputs to the value specified by `LPM_AVALUE`, if that value is present, or sets the `q[]` outputs to all 1s.
`aload`	No	Asynchronous load input. Asynchronously loads the flipflop with the value on the data input.	If omitted, the default is `0`. If `aload` is used, `data` must be used.
