[Reading (writing) of context table RAM continues during this time.]

RAM data is outputted (inputted) by way of data read (write) buffer.

The RAM address is automatically incremented every time 1 byte is read out (write in).

Note: It is not possible to mix reading and writing.

Note: The assignment of address for context table RAM is as follows

Internal context mode: Address 0 to 1023 of (LSB: 0, MSB: 9) as shown below.

External context mode: Address 0 to 4095 of (LSB: CX0, MSB: CS11)

(AT pixel is MSB: 9)
