Clock driver for Motorola
MVME68K Single Board Computers
SYNOPSIS
clock0 at pcc? ipl 5
clock0 at pcctwo? ipl 5
DESCRIPTION
The
clock driver uses the counter/timer facilities of the
MVME147's
pcc driver or the MVME167/MVME177's
pcctwo driver to provide two independent hardware clocks for
use by the
NetBSD kernel.
Both clock interrupts are set to 100Hz, with one used to provide the master
kernel stats clock tick. The other is used for profiling purposes.
