所有四个串行端口都使用位于上TRVC062105000 TRVC070938000 TRVC070938005.A的EIA-232-D驱动器和接收器，并且所有信号线都路由到I/O连接器。❏ 串行端口1是一个最低功能异步端口。它使用RXD、CTS、TXD和RTS。❏ 串行端口2和3是全功能异步端口。它们使用RXD、CTS、DCD、TXD、RTS和DTR。
串行端口4是一个全功能异步或同步端口。它可以以高达每秒64k比特的同步比特率运行。它使用RXD、CTS、DCD、TXD、RTS和DTR。它还与同步时钟信号线接口。
板硬件将来自CD2401的DTR信号连接到连接器P2处标记为RTS的引脚。同样地，来自CD2401的RTS被绑定到P2上的DTR。因此，在对CD2401进行编程时，当需要RTS时断言DTR，当需要DTR时断言RTS。
PCCchip2提供的接口允许16位CD2401出现在连续地址处。TRVC062105000 TRVC070938000 TRVC070938005.A
对CD2401的访问必须是8位或16位：不允许32位访问。TRVC062105000 TRVC070938000 TRVC070938005.A
英文资料：
All four serial ports use EIA-232-D drivers and receivers located on the , and all the signal lines are routed to the I/O connector. ❏ Serial port 1 is a minimum function asynchronous port. It uses RXD, CTS, TXD, and RTS. ❏ Serial ports 2 and 3 are full function asynchronous ports. They use RXD, CTS, DCD, TXD, RTS, and DTR.TRVC062105000 TRVC070938000 TRVC070938005.A
Serial port 4 is a full function asynchronous or synchronous port. It can operate at synchronous bit rates up to 64 k bits per second. It uses RXD, CTS, DCD, TXD, RTS, and DTR. It also interfaces to the synchronous clock signal lines.
The board hardware ties the DTR signal from the CD2401 to the pin labeled RTS at connector P2. Likewise, RTS from the CD2401 is tied to DTR on P2. Therefore, when programming the CD2401, assert DTR when you want RTS, and RTS when you want DTR.TRVC062105000 TRVC070938000 TRVC070938005.A
The interface provided by the PCCchip2 allows the 16-bit CD2401 to appear at contiguous addresses.
Accesses to the CD2401 must be 8 or 16 bits: 32-bit accesses are not permitted.
