SLOW Mode
The SLOW mode function is controlled by the SM bit in the Miscellaneous Control Register. When
the SM bit is set, the internal bus clock is divided by 16, resulting to a frequency equal to the
oscillator frequency divide by 32. This feature permits a slow down of all the internal operations
and thus reduces power consumption — particularly useful while in WAIT mode. The SM bit is
automatically cleared while going to STOP mode.
SM — Slow Mode
1 (set)
Slow mode enabled. Internal bus frequency fOP=fOSC ÷ 32.
0 (clear) –
Slow mode disabled. Internal bus frequency fOP=fOSC ÷ 2.
