MOTOROLA

MC68CK338TS/D

1. Privileged instruction.

2. Two LPSTOP modes are supported. The first LPSTOP mode is the normal LPSTOP in which the system clock

on the chip is stopped, shutting down all IMB modules with the exception of some parts of the SIML and

CLKOUT. The second LPSTOP mode causes the system clock to be stopped only at the CPU32L, when the

LPSTOP instruction is executed by the CPU32L. As with the normal LPSTOP operation, the CPU32L can be

restarted by an interrupt, a trace, or a reset exception.
