# scc(4)

Serial Communications Controller driver

## NAME

**scc** – Serial Communications Controller driver

## SYNOPSIS

**device scc** **device uart**

## DESCRIPTION

The **scc** device driver provides support for various classes of SCCs. It is an umbrella driver that delegates control of each independent communication channel to subordinate drivers. These subordinate drivers, like [uart(4)](/uart/4.md), take care of the details of the communication itself.

## HARDWARE

The **scc** driver supports the following classes of Serial Communications Controllers:

- QUICC: Freescale/NXP QUad Integrated Communications Controllers.

- Z8530: Zilog 8530 based serial communications controllers.

## SEE ALSO

[puc(4)](/puc/4.md), [uart(4)](/uart/4.md)

## HISTORY

The **scc** device driver first appeared in FreeBSD 7.0.

## AUTHORS

The **scc** driver and this manual page were written by Marcel Moolenaar ⟨*marcel@xcllnt.net*⟩.
