<p>PROBLEM TO BE SOLVED: To process with preference a battery related interrupt by giving a command to a sub-CPU from a main CPU to temporarily stop the transfer of the coordinate data on a touch panel when the battery related interrupt occurs. SOLUTION: A sub-CPU 4 is connected to a bus 8, and the data on a touch panel 5 and a battery control part 6 are transferred. Then the interrupts of the panel 5 and a battery are processed by a main CPU 1 via a system G/A 2. The CPU 1 gives a command to the sub-CPU 4 to temporarily stop the transfer of the coordinate data on the panel 5. When a battery related interrupt occurs, the transfer of the coordinate data is temporarily stopped by a processing routine of the battery related interrupts. Then a command is issued for reading the interrupt factor, and this factor is decided by the answer given to the command.</p> |
