Abstract
The invention provides a personal data assistant terminal with radio having data transmission and reception functions by a radio wave wherein the applied power supply mode of a CPU can be changed over to a power supply mode required by a peripheral circuit to the CPU. When a power supply mode change-over signal representing a power supply mode which is to be entered subsequently and a power supply mode defining signal for defining the power supply mode represented by the power supply mode change-over signal are inputted from the outside to a power supply control section of a CPU, a CPU core in the CPU changes over the applied power supply mode of the CPU to the power supply mode represented by the power supply mode change-over signal.
Claims4
A personal data assistant terminal with radio which has data transmission and reception functions by a radio wave and a plurality of different power supply modes, comprising:
- a CPU for effecting power supply control of said personal data assistant terminal with radio;
- said CPU having a terminal for receiving, as an input signal thereto, a power supply mode change-over signal representative of a power supply mode which is to be entered subsequently by said CPU, and another terminal for receiving, as an input signal thereto, a power supply mode defining signal for defining a power supply mode represented by the power supply change-over signal.
