138 11.2 Introduction
Clock generation circuitry generates the internal and external ECLK
signals as well as internal clock signals used by the CPU and on-chip
peripherals. A clock monitor circuit, a computer operating properly
(COP) watchdog circuit, and a periodic interrupt circuit are also
incorporated into the MC68HC912D60A.
