CHAPTER 10
SPECIAL OPERATING MODES
The 8XC196Lx’s idle and powerdown modes are the same as those of the 8XC196Kx. However,
the clock circuitry has changed, and the on-circuit emulation (ONCE) special-purpose mode op-
eration has changed slightly because of the new reset state pin levels that have been implemented.
10.1 INTERNAL TIMING
The 87C196LA and LB clock circuitry (Figure 10-1) implements a phase-locked loop and clock
multiplier circuitry, which can substantially increase the CPU clock rate while using a lower-fre-
quency input clock.
