# mux8(9)

Select from one of eight input values

## NAME

mux8 - Select from one of eight input values

## SYNOPSIS

**loadrt mux8 \[count=*N*\|names=*name1*\[,*name2...*\]\]**

## FUNCTIONS

- **mux8.***N* (requires a floating-point thread)

  ## PINS

- **mux8.*N*.sel0 bit in**

  - **mux8.*N*.sel1 bit in**

  - **mux8.*N*.sel2 bit in**

  Together, these determine which **in***N* value is copied to **out**.

- **mux8.*N*.out float out**

  Follows the value of one of the **in***N* values according to the three **sel** values

  - **sel2=FALSE**, **sel1=FALSE**, **sel0=FALSE**

    **out** follows **in0**

  - **sel2=FALSE**, **sel1=FALSE**, **sel0=TRUE**

    **out** follows **in1**

  - **sel2=FALSE**, **sel1=TRUE**, **sel0=FALSE**

    **out** follows **in2**

  - **sel2=FALSE**, **sel1=TRUE**, **sel0=TRUE**

    **out** follows **in3**

  - **sel2=TRUE**, **sel1=FALSE**, **sel0=FALSE**

    **out** follows **in4**

  - **sel2=TRUE**, **sel1=FALSE**, **sel0=TRUE**

    **out** follows **in5**

  - **sel2=TRUE**, **sel1=TRUE**, **sel0=FALSE**

    **out** follows **in6**

  - **sel2=TRUE**, **sel1=TRUE**, **sel0=TRUE**

    **out** follows **in7**

- **mux8.*N*.in0 float in**

  - **mux8.*N*.in1 float in**

  - **mux8.*N*.in2 float in**

  - **mux8.*N*.in3 float in**

  - **mux8.*N*.in4 float in**

  - **mux8.*N*.in5 float in**

  - **mux8.*N*.in6 float in**

  - **mux8.*N*.in7 float in**
