(b) Interruption control
It controls LSI inside interruptions, external interruptions and interruptions from an external interface as outputs for the
MPU.
(c) Memory control
DRAM and SRAM control, chip select output control of ROM, flash memory and MUPIS, and bank switch control for
expanding their memory spaces.
(d) Print control
It creates a print timing corresponding to the print DPI to control the position and print correction for pins. This also
controls the print Mask and DMAC which reads print data from the memory and transmits it to the print output buffer.
(e) External interface
It controls various interfaces for main LSI, IEEE1284, serial, MUPIS, OpePaneLSI, EEPROM.
(f) Motor drive interface
Each control of OVDV pulse generation for AG motor, generation of pulse for switching ribbon motor phase, and OVDV
pulse generation for LF motor.
(8) Sub LSI (IC17, IC18: MSM72V017)
This LSI is the I/O port LSI which controls the input/output of various controlling signals with command inputs from the
MPU.
(a) Sub LSI #1 (IC17: MSM72V017)
Input/output control for controlling signals to various sensors, FAN controlling signals, sensor slice level controlling
signals, AG motor controlling signals, and LF motor controlling signals.
(b) Sub LSI #2 (IC18: MSM72V017)
Input/output control for controlling signals to various sensors, SP motor current controlling signals, external interface
controlling signals, TR motor controlling signals, bail motor controlling signals, cutter motor (for optional connection)
controlling signals.
(9) Serial I/F LSI (IC35: 85L30)
This LSI is the serial I/F LSI which controls the input/output of serial I/F controlling signals with command inputs from the
MPU.
