CPU Module Specifications
Note 1: When using a 64KB memor y car tridge and WindLDR ver. 4.2 or higher.
Note 2: When using a CPU module with system program ver. 201 or higher and WindLDR ver. 4.2 or higher.
System Statuses at Stop, Reset, and Restart
Note: All expansion data registers are keep types. AS-Inter face operands (M1300-M1977 and D1700-D1999) remain
unchanged when the reset input is turned on.
