POWER DOWN MODE (I) ••••••••• Data Hold Mode in RAM
The operation of oscillation circuit is suspended by setting
Ps
terminal to
low level after RESET terminal has been set to low level. Consequently, all
the data in RAM area can be held in low power consumption.
The minimum hold voltage of VCC in this mode is 2V.
PS terminal is set to
~
level to resume oscillation after VCC has been
reset to SV, and then RESET terminal is set to high level, thus, the normal
mode is restarted from the initialize operation (address 0).
