Instructions acceptable
1. — indicates no effect.
* After execution of the CGRAM/DDRAM data write or read instruction, the RAM address
counter is incremented or decremented by 1. The RAM address counter is updated after the
busy flag turns off. In Figure 17, t
ADD
is the time elapsed after the busy flag turns off until the
address counter is updated.
2. Extension time changes as frequency changes. For example, when f is 300 kHz, the execution
time is: 37 μs
×
270/300 = 33 μs.
3. Execution time in a low-power mode (LP = 1 and EXT = low) becomes four times for a 1-line
mode, and twice for a 2- or 4-line mode.
