(1) Centronics parallel interface
Received data DATA1 to DATA8 is latched to the internal MPU register just after the falling edge of the Strobe
signal *DSTB. The BUSY signal goes high.
The MPU recognizes that data has been received and stores the information in the receive buffer or processes it
immediately. After the operation finishes, the MPU issues the *ACK signal and the BUSY signal goes low.
