Read, Write, and Control Registers

The DMC-1800 provides four registers used for communication. The main communications FIFO register for sending commands and receiving responses occupies address N. The control register used to monitor the main communications status occupies address N+4. The reset register occupies address N+8 and is used for resetting the controller and/or main read/write FIFO registers as well as retrieving the interrupt status byte. The secondary FIFO for accessing the data record occupies address N+C.

Communication with DMC-1800

Register	Address	Read/Write	Description
Main FIFO	N	Read / Write	Send commands and receive responses

CONTROL	N+4	Read / Write	For FIFO status control
IRQ / RESET	N+8	Read / Write	For IRQ status byte and controller reset
Secondary FIFO	N+C	Read only	For data record access

Simplified Communication Procedure

The simplest approach for communicating with the DMC-1800 is to check bits 0 and 2 of the CONTROL register at address N+4. Bit 0 is for WRITE STATUS and bit 2 is for READ STATUS.

Read Procedure - To receive data from the DMC-1800, read the control register at address N+4 and check bit 2. If bit 2 is zero, the DMC-1800 has data to be read in the READ register at address N. Bit 2 must be checked for every character read.

Write Procedure - To send data to the DMC-1800, read the control register at address N+4 and check bit 0. If bit 0 is zero, the DMC-1800 FIFO buffer is not full and a character may be written to the WRITE register at address N. If bit 0 is one, the buffer is full and any additional data will be lost.

Any high-level computer language such as C, Basic, Pascal or Assembly may be used to communicate with the DMC- 1800 as long as the READ/WRITE procedure is followed as described above, so long as the base address is known.
