8 Interface

Parallel and RS-232 Serial interfaces are available on this module.

8.1 Interface timing

8.1.1 Parallel interface timing 1 (Not applicable for bit image data transfer in DMA mode)

Note: RDY=0 (BUSY) is output after every byte.

Internal receive buffer capacity is 256 bytes. After data is input, RDY signal is immediately set to

RDY=0 (BUSY) until the received byte is stored to the receive buffer. If the internal receive buffer is

full, RDY signal will remain BUSY until space for 1 byte becomes available. The required time for

this varies, depending on the type of commands and rate at which data is input. The RDY signal

should always be checked before writing data.
