'[OT]: LCD in 4 Bit mode'

Hi Guys
I have a stupid question now.
I want to use LCD in 4 bit mode.
I wonder how to send the character!!!! the character is 8 bit.
I could estimate form the datasheet ( which is in german) that I send the
higher 4 bits first then the lower 4 next.
Is that true???
If true,does that mean to send the higher then the lower after it
directly!!!!!
Thanks

both nybbles have been sent
