8.0 Registers (Continued) Table II shows the contents of the MSR. Details on each bit follow. Bit 0: This bit is the Delta Clear to Send (DCTS) indicator. Bit 0 indicates that the CTS input to the chip has changed state since the last time it was read by the CPU. Bit 1: This bit is the Delta Data Set Ready (DDSR) indicator. Bit t indicates that the DSR input to the chip has changed state since the last time it was read by the CPU. Bit 2: This bit is the Trailing Edge of Ring Indicator (TERI) detector. Bit 2 indicates that the RI input to the chip has changed from a low to a high state. Bit 3: This bit is the Delta Data Carrier Detect (DDCD) indicator. Bit 3 indicates that the DCD input to the chip has changed state. Note: Whenever bit 0, I, 2, or 3 is set to logic I, a MODEM Status Interrupt is generated. Bit 4: This bit is the complement of the Clear to Send (CTS) input. If bit 4 (loop) of the MCR is set to a 1, this bit is equivalent to RTS in the MCR. Bit 5: This bit is the complement of the Data Set Ready (DSR) input. If bit 4 of the MCR is set to a 1, this bit is equivalent to DTR in the MCR. Bit 6: This bit is the complement of the Ring Indicator (RI) input. If bit 4 of the MCR is set to a 1, this bit is equivalent to OUT 1 in the MCR. Bit 7: This bit is the complement of the Data Carrier Detect (DCD) input. If bit 4 of the MCR is set to a 1, this bit is equivalent to OUT 2 in the MCR. B.9 SCRATCHPAD REGISTER This 8-bit Read/Write Register does not control the UART in any way. It is intended as a scratchpad register to be used by the programmer to hold data temporarily. 9.0 Typical Applications This shows the basic connections of an NS16450 to an NS32016 CPU All- A231:::============:;-;=:>AlB-A23 Al-A3 ~~=~~AO-A2 XlN 'OUT 16 ALTERNATE XTAlCONTROL I CJ-=- 1&32018 C"' iIiIi ADDRESS 14 DECODER +5 CSl -RClK i!TII m IIOTl RS-232 CONNECTlIt " lliifl IIIf/iIiT 00-07 00-07 N518450 IUART) Ii ..2!-..+5V J8 m 37 Olli 36 m SOUl NS32201 TCU ~~-------------i r------~21~IM WIIi--------------i 1-______ "'18~IWIi 00-015 SIN INTR CSOUl OOiS NC " +5V IVCCI TLlC/8401-14 4-33
