(6) Main LSI (IC38: MSM91U036)
MSM91U036 is control LSI for head data, DC motor and modification of print data, which has the following functions.
(a) Head data control
It distributes print data stored in the DRAM over wire arrangements of the print head and outputs it as dot data in
synchronism with print timing. In this time, the distribution complies with each print mode which is specified by the MPU.
(b) Print timing control
It outputs the signals which control the print timing of ODD and EVEN pins on the print head.
(c) Space motor speed control function
It controls the space motor with micro-programs to accelerate/decelerate it. This LSI also controls the speed of the space
motor in agreement with each print mode.
