D0 to D119: Instruction data
The data is acquired on the rising edge of the CL signal and latched on the falling edge of the CE signal. When
transferring instruction data from the microcontroller, applications must assure that the time from the transfer of one set
of instruction data until the next instruction data transfer is significantly longer than the instruction execution time.
