Control Circuit
Figure 2-10 gives the control circuit block diagram for the DLQ-3000. The BOARD ASSY., C124 MAIN is located at the center. The printer uses a 16-bit internal 8-bit external 1-chip CPU piPD70433 V55PI ICIO as the main CPU, with a clock frequency of 24.8832 MHz CR1 . The control program is stored in a 1Mbit Flash EEPROM Intel 28F010 IC13 . The CPU starts the program after an external reset signal is received. The program can be reloaded by PC. For memory, two D-RAM's are used for external PSRAM....
