10.3.2
Transition to Software Standby Mode: The LSI switches from a program execution state to a
software standby mode by executing the SLEEP instruction when the STBY bit is 1 in STBCR. In
a software standby mode, not only the CPU but also the clock and on-chip peripheral modules
halt. The clock output from the CKIO pin also halts.
The contents of the CPU and cache registers remain unchanged. Some registers of on-chip
peripheral modules are, however, initialized. Table 10.3 lists the states of on-chip peripheral
modules registers in software standby mode.
