Description
Executi
on Time
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
Write data X 1 0 D7 D6 D5 D4 D3 D2 D1 D0 Write data into internal RAM
(DDRAM / CGRAM / SEGRAM).
Read data X 1 1 D7 D6 D5 D4 D3 D2 D1 D0 Read data from internal RAM
(DDRAM / CGRAM / SEGRAM).
(fosc =
270kHz)
43µs
43µs
NOTES:
1. When an MPU program with busy flag (DB7) checking is made, 1/2 fosc (is necessary) for executing the next instruction
by the falling edge of the "E" signal after the busy flag (DB7) goes to "Low"
2. "X" Don’t care
