.SH NAME

mux4 \- Select from one of four input values
.SH SYNOPSIS
.HP
.B loadrt mux4 [count=\fIN\fB|names=\fIname1\fB[,\fIname2...\fB]]
.SH FUNCTIONS
.TP
\fBmux4.\fIN\fB\fR (requires a floating-point thread)

.SH PINS
.TP
.B mux4.\fIN\fB.sel0\fR bit in \fR
.br
.ns
.TP
.B mux4.\fIN\fB.sel1\fR bit in \fR
Together, these determine which \fBin\fIN\fR value is copied to \fBout\fR.

.TP
.B mux4.\fIN\fB.out\fR float out \fR
Follows the value of one of the \fBin\fIN\fR values according to the two \fBsel\fR values
.RS
.TP
\fBsel1=FALSE\fR, \fBsel0=FALSE\fR
\fBout\fR follows \fBin0\fR
.TP
\fBsel1=FALSE\fR, \fBsel0=TRUE\fR
\fBout\fR follows \fBin1\fR
.TP
\fBsel1=TRUE\fR, \fBsel0=FALSE\fR
\fBout\fR follows \fBin2\fR
.TP
\fBsel1=TRUE\fR, \fBsel0=TRUE\fR
\fBout\fR follows \fBin3\fR
