Bus Operation
7.8.2.1 LPSTOP BROADCAST CYCLE. The execution of an LPSTOP instruction gener-
ates the LPSTOP broadcast cycle. This access is a write bus cycle and is indicated with
TT1, TT0 = $3, A31–A0 = $FFFFFFFE, and TM2–TM0 = $0. When an external device ter-
minates the cycle with either TA or TEA, the processor enters the low-power stop mode. A
