Stop Clock Feature
The 9154A-43 incorporates a unique stop clock feature compatible with static logic processors. When the stop clock pin goes
low, the 2XCPUCLK will go low after the next occurring falling edge. When STOPCLK again goes high, 2XCPUCLK resumes
on the next rising edge of the internal clock. This feature enables fast, glitch-free starts and stops of the 2XCPUCLK and is
guaranteed that the CPU does not receive any short period clocks.
