/*
 * 86Box	A hypervisor and IBM PC system emulator that specializes in
 *		running old operating systems and software designed for IBM
 *		PC systems and compatibles from 1981 through fairly recent
 *		system designs based on the PCI bus.
 *
 *		This file is part of the 86Box distribution.
 *
 *		ICD2061 clock generator emulation header.
 *		Also emulates the ICS9161 which is the same as the ICD2016,
 *		but without the need for tuning (which is irrelevant in
 *		emulation anyway).
 *
 *		Used by ET4000w32/p (Diamond Stealth 32) and the S3
 *		Vision964 family.
