5 / 72 page  xr XR17D158 REV. 1.2.1 UNIVERSAL (3.3V AND 5V) PCI BUS OCTAL UART 5 RTS4# 86 O UART channel 4 Request to Send or general purpose output (active low). CTS4# 82 I UART channel 4 Clear to Send or general purpose input (active low). DTR4# 87 O UART channel 4 Data Terminal Ready or general purpose output (active low). DSR4# 83 I UART channel 4 Data Set Ready or general purpose input (active low). CD4# 84 I UART channel 4 Carrier Detect or general purpose input (active low). RI4# 85 I UART channel 4 Ring Indicator or general purpose input (active low). TX5 80 O UART channel 5 Transmit Data or infrared transmit data. Normal TXD output idles HIGH while infrared TXD output idles LOW. RX5 71 I UART channel 5 Receive Data or infrared receive data. Normal RXD input idles HIGH. The infrared pulses typically idle LOW but can be inverted inter- nally prior the decoder by FCTR[4]. RTS5# 78 O UART channel 5 Request to Send or general purpose output (active low). CTS5# 72 I UART channel 5 Clear to Send or general purpose input (active low). DTR5# 79 O UART channel 5 Data Terminal Ready or general purpose output (active low). DSR5# 75 I UART channel 5 Data Set Ready or general purpose input (active low). CD5# 76 I UART channel 5 Carrier Detect or general purpose input (active low). RI5# 77 I UART channel 5 Ring Indicator or general purpose input (active low). TX6 62 O UART channel 6 Transmit Data or infrared transmit data. Normal TXD output idles HIGH while infrared TXD output idles LOW. RX6 55 I UART channel 6 Receive Data or infrared receive data. Normal RXD input idles HIGH. The infrared pulses typically idle LOW but can be inverted inter- nally prior the decoder by FCTR[4]. RTS6# 60 O UART channel 6 Request to Send or general purpose output (active low). CTS6# 56 I UART channel 6 Clear to Send or general purpose input (active low). DTR6# 61 O UART channel 6 Data Terminal Ready or general purpose output (active low). DSR6# 57 I UART channel 6 Data Set Ready or general purpose input (active low). CD6# 58 I UART channel 6 Carrier Detect or general purpose input (active low). RI6# 59 I UART channel 6 Ring Indicator or general purpose input (active low). TX7 54 O UART channel 7 Transmit Data or infrared transmit data. Normal TXD output idles HIGH while infrared TXD output idles LOW. RX7 47 I UART channel 7 Receive Data or infrared receive data. Normal RXD input idles HIGH. The infrared pulses typically idle LOW but can be inverted inter- nally prior the decoder by FCTR[4]. RTS7# 52 O UART channel 7 Request to Send or general purpose output (active low). CTS7# 48 I UART channel 7 Clear to Send or general purpose input (active low). DTR7# 53 O UART channel 7 Data Terminal Ready or general purpose output (active low). DSR7# 49 I UART channel 7 Data Set Ready or general purpose input (active low). PIN DESCRIPTIONS NAME PIN #TYPE DESCRIPTION |
