# NAME

`mfp` — X68K Multi-function Peripherals

# SYNOPSIS

`mfp0 at intio0 addr 0xe88000 size 0x2000 intr 64`

# DESCRIPTION

`mfp` drives Motorola MC68901 MFP (Multi-function Peripheral). `mfp` driver is always required to run the NetBSD/x68k kernel, because it is connected to important devices such as the display controller, and provides fundamental functions like the system clock tick and interrupt controller. Since `mfp` provides many functions, most of the jobs as a device driver is done by its child drivers such as kbd(4) and clock(4). `mfp` driver itself only provides the common way to access its registers and a few utility functions for other non-child drivers.

Machine-dependent part and machine-independent part should be split.
