Abstract

PURPOSE: To attain IPL on disappearance of a battery-support-mode indication flag, by reading the flag, stored in a memory when a unit power supply is turned off, at the time of feeding power.
CONSTITUTION: When unit power supply 15 is put to work, access to battery-support mode indication flag memory part 22 of RAM5 is attained and in case of a logic-"1" level, battery-support-mode flag storage register 21 of refresh control part 14 is read, so that only when it is in effect, a selector circuit will put TTL refresh control circuit 19 into operation instead of CMOS refresh control circuit 20. Then, when an error is found in the contents of RAM through the read check process of RAM5, IPL is started. On the other hand, if indication flag memory part 22 is logic "0", battery power supply 16 is started to be charged before IPL.
