Section 24 Power-Down Modes
24.2.4
Transition to Hardware Standby Mode: When the STBY pin is driven low, a transition is made
to hardware standby mode from any mode.
In hardware standby mode, all functions enter the reset state and stop operation, resulting in a
significant reduction in power dissipation. As long as the prescribed voltage is supplied, on-chip
RAM data is retained. I/O ports are set to the high-impedance state.
In order to retain on-chip RAM data, the RAME bit in SYSCR should be cleared to 0 before
driving the STBY pin low. Do not change the state of the mode pins (MD2 to MD0) while this
LSI is in hardware standby mode.
