Section 20 Power-Down State
20.5
20.5.1
Regardless of its current state, the chip enters hardware standby mode whenever the
goes low. Hardware standby mode reduces power consumption drastically by halting all functions
of the CPU, and on-chip supporting modules. All modules are reset except the on-chip RAM. As
long as the specified voltage is supplied, on-chip RAM data is retained. I/O ports are placed in the
high-impedance state.
Clear the RAME bit to 0 in SYSCR before
The inputs at the mode pins (MD2 to MD0) should not be changed during hardware standby
mode.
20.5.2
Hardware standby mode is exited by inputs at the
