Datasheet

Note 4: When using the MSB=0 command, a Status Read must be performed.
If a status check is not carried out, the RA6963 cannot operate normally, even after a
delay time.
The hardware interrupt occurs during the address calculation period (at the end of each
line).
If a MSB=0 command is sent to the RA6963 during this period, the RA6963 enters Wait
status.
If a status check is not carried out in this state before the next command is sent, there is
the possibility that command or data will not be received.
• Setting Data
When using the RA6963, first set the data, then set the command.
Note: When sending more than two data, the last datum (or last two data) is valid.
