The 2-byte successive command writes characters to the video RAM. To successively write characters without
changing the blinking data, reverse specification data, and V
C2
specification data, first transfer the first byte and then
transfer the second byte (character address).
To change the contents of the above data, change the contents of the data and then input the command from the
first byte after terminating the 2-byte successive command once (by either making CS high or transferring the 2-byte
successive command end code).
However, the command cannot be transferred successively across banks.
When the low-order bank is selected, the command can be transferred successively in a character address range
of 000H to 0FFH; when the high-order bank is selected, the character address range is from 100H to 1FFH.
It is recommended that characters that are frequently used be stored to both the high-order and low-order banks.
To write a character that across the banks, complete successive transfer once, and then transfer the command
from the first byte after changing the bank.
