INSTRUCTION DESCRIPTION
NOTES
:
1.
For the NOP instruction,
when EV mode is
0
(32 contrast-step), the NOP instruction set is (000000000), and
when EV mode is
1
(64 contrast-step), the NOP instruction set is (000000001).
2.
Instruction execution time depends on the internal process time of KS0090, therefore it is necessary to provide a time
larger than one MPU interface cycle time (tc) between execution of two successive instructions.
