4.4 CONTINUOUS INPUT OF COMMAND
Transfer each of the 1-byte, 2-byte, and 2-byte successive commands from a microcontroller to the
μ
PD6461, 6462
as follows.
To transfer a 1-byte or 2-byte command, or a 2-byte successive command with blinking data changed after a 2-
byte successive command has been transferred, either make CS high once, or transfer 2-byte successive command
end code (FFH:
μ
PD6461/7FH:
μ
PD6462) at the end of the 2-byte successive command. In the latter case, it is not
necessary to make CS high.

It is not necessary to make CS low and then back high again.
Remark
By using the 2-byte successive command end code, the CS pin may remain low. However, it is
recommended to make CS pin high to improve the noise immunity.
