7 / 16 page  MD192 7 Synchronous Receiver Transmitter (SOPIF) One synchronous only serial interface (SOPIF) is built into the MFC1000, allowing the MFC1000 to communicate with the external operator panel module and with other external peripherals. The SOPIF provides separate signals for Data (SSTXD, SSRXD), Clock (SSCLK), and optional Data Request / Data Acknowledge (SSREQ/SSACK). It is a full duplex, three-wire system. The SOPIF may be configured to operate as either a master or slave interface. The bit rate, clock polarity, clock phase, and data shifting order are programmable. Synchronous/Asynchronous Receiver Transmitter (SASIF) One Synchronous/Asynchronous serial interface (SASIF) which performs serial-parallel conversion on data received from a peripheral device and parallel- to-serial conversion of data for transmission to a peripheral device. The interface consists of serial transmit data (SASTXD), serial receive data (SASRXD), and a serial clock (SASSCLK) signals. The SASIF includes a programmable bit rate generator for asynchronous and synchronous operations. The data shifting order, Data bit number, and the SASSCLK polarity are programmable. Real-Time Clock (RTC) The MFC1000 includes a battery backup real-time clock. The RTC automatically maintains the correct date and time for 32 years. The leap year compensation is included. A 32.768 kHz or 65.536 kHz watch crystal is required by the RTC. Tone/Bell/Ring Generator The MFC1000 provides three programmable clock generator outputs. Two of the generators are used as tone generators and the third as a bell or ring driver. General Purpose Inputs and/or Outputs The MFC1000 provides up to 15 GPIO’s and 8 GPO's. 1284 Bi-directional Parallel Interface An IEEE 1284 compatible bi-directional peripheral parallel port is provided. Compatibility, nibble, byte, and ECP modes are supported. The Parallel I/O interface can be programmed to support CPU or DMA data transfers. DMA is available in Compatibility, nibble, and ECP modes. Autobaud An autobaud circuit supports detection of baud rate and data structure (parity and character length) for programming an external UART. A precision timer, shift register and edge detector are included to determine the width of the start bit and to sample the serial data stream. Serial data rates up to 115.2 KBPS are supported. Watchdog Timer The Watchdog Timer guards against firmware lockup on the part of either Executive-controlled background tasks or interrupt-driven tasks, and can be only enabled by a sequence of events under control of the Watchdog Control Logic. Once the Watchdog Timer has been enabled, it can not be disabled unless a system reset occurs. Reset and Power Control The BATRSTn input initializes the MFC1000 at power-on. An externally generated power-down input, PWRDWNn, controls switching between primary and battery power. The open drain RESETn I/O pin provides a reset output to external circuits, or can accept an externally generated reset. The external reset will not reset the RTC. Separate DRAM and RTC battery power inputs are provided for battery-backed up functions. |
