Note:
6.2.1
In sleep mode, CPU operation is halted but the on-chip peripheral modules function at the clock
frequency set by the MA2, MA1, and MA0 bits in SYSCR2. CPU register contents are retained.
When an interrupt is requested, sleep mode is cleared and interrupt exception handling starts.
Sleep mode is not cleared if the I bit of the condition code register (CCR) is set to 1 or the
requested interrupt is disabled in the interrupt enable register. After sleep mode is cleared, a
transition is made to active mode when the LSON bit in SYSCR2 is 0, and a transition is made to
subactive mode when the bit is 1.
*
Registers can be read or written in subactive mode.
