Parallel interface timing 2 (Applicable for bit image data transfer in DMA mode)
RS-232 Asynchronous serial interface timing
Note: Monitoring RDY signal is not necessary for bit image data transfer in DMA mode.
The above timing is RS-232 level. Logical value is the inverse of the above. (VsIH:0, VsIL:1)
