Quad UART (QUART) The MVME7100 contains one Quad UART device connected to the MC864xD device control bus to provide additional asynchronous serial ports. The Quad UART provides four asynchronous serial ports which are routed to the P2 connector. The TTL-level signals of RX, TX, CTS, and RTS from each port are routed through on-board RS-232 drivers and receivers to the P2 connector where the signals can be picked up by a transition module. The reference clock frequency for the QUART is 1.8432MHz. All UART ports are capable of signaling at up to 115 Kbaud. Refer to the ST16C554D data sheet for additional details and/or programming information.PLD provides the following functions on the board: ? Local bus address latch ? Chip selects for flash banks, MRAM, and Quad UART ? System control and status registers ? Four 32-bit tick timers ? Watch Dog Timer ? RTC 1MHz reference cloc
