NOTES
1. Instruction execution time depends on the internal process time of S6A0031, therefore it is necessary to provide a time larger
than one MPU interface cycle time (tc) between execution of two successive instructions.
2. "Clear Display" instruction has 850
μ
s execution time (when fosc = 40.0kHz), so check the Busy flag or wait for more than
850
μ
s after using "Clear Display" instruction.
