Regardless of its current state, the chip enters hardware standby mode whenever the
goes low.
Hardware standby mode reduces power consumption drastically by halting the CPU, stopping all
the functions of the on-chip supporting modules, and placing I/O ports in the high-impedance
state. The registers of the on-chip supporting modules are reset to their initial values. Only the on-
chip RAM is held unchanged, provided the minimum necessary voltage supply is maintained.
Notes: 1. The RAME bit in the system control register should be cleared to 0 before the STBY

Recovery from the hardware standby mode requires inputs at both the STBY and RES pins. When

time and should be held low long enough for the clock to stabilize. When the RES pin changes
from low to high, the reset sequence is executed and the chip returns to the program execution
state.
