Chapter 4 – SocketModem Parallel Interface – A Programmer’s Description Chapter 4 – SocketModem Parallel Interface – A Programmer’s Description SocketModem Parallel Interface Internal Registers The SocketModem parallel interface is a mimic of a 16C550A UART. It is similar to the MIMIC interface used in the Zilog Z80189. The SocketModem mimic (MMM) takes advantage of this standard interface while replacing the serial to parallel data transfer with a less complicated parallel to parallel data tran

Chapter 4 – SocketModem Parallel Interface – A Programmer’s Description FIFO Operation The 16-byte transmit and receive data FIFOs are enabled by the FIFO Control Register (FCR) bit-0. You can set the receive trigger level via FCR bits 6/7. The receiver FIFO section includes a time-out function to ensure data is delivered to the external host. An interrupt is generated whenever the Receive Holding Register (RHR) has not been read following the loading of a character or the receive trigger level

Chapter 4 – SocketModem Parallel Interface – A Programmer’s Description Time Out Interrupts The interrupts are enabled by IER bits 0-3. Care must be taken when handling these interrupts. Following a reset the transmitter interrupt is enabled, the SocketModem will issue an interrupt to indicate that transmit holding register is empty. This interrupt must be serviced prior to continuing operations. The LSR register provides the current singular highest priority interrupt only. A condition can exis

Chapter 4 – SocketModem Parallel Interface – A Programmer’s Description RBR Receive Buffer (RX FIFO) All eight bits are used for receive channel data (host read/data in; host write/data out). The three error bits per byte are copied into bits 2, 3, and 4 of the LSR during each host I/O read; therefore, they are available for monitoring on a per-byte basis.

Chapter 4 – SocketModem Parallel Interface – A Programmer’s Description FCR FIFO Control Bits 6–7: Used to determine RX FIFO trigger levels. Bit 5: Used to detect a change in the FCR. Bit 4: TX FIFO overrun bit. Bit 3: DMA mode select. If bit 3 is a 0, the 16450 mode is enabled which does only single-byte transfers. When bit 3 is a 1, it enables a multiple byte (FIFO mode) data transfer. Bit 2: TX FIFO reset. This will cause TX FIFO pointer logic to be reset (any data in TX FIFO will be lost). T
