UNIVERSAL (3.3V AND 5V) PCI BUS DUAL UART
á
REV. 1.2.0
4
DSR0#
68
I
UART channel 0 Data Set Ready or general purpose input (active low). This
input should be connected to VCC when not used.
CD0#
69
I
UART channel 0 Carrier Detect or general purpose input (active low). This
input should be connected to VCC when not used.
RI0#
70
I
UART channel 0 Ring Indicator or general purpose input (active low). This
input should be connected to VCC when not used.
TX1
62
O
UART channel 1 Transmit Data or infrared transmit data. Normal TXD output
idles HIGH while infrared TXD output idles LOW.
UART channel 1 Receive Data or infrared receive data. Normal RXD input
idles HIGH while infrared RXD input idles LOW. In the infrared mode, the
polarity of the incoming RXD signal can be selected via FCTR bit-4. If this bit
is a logic 0, a LOW on the RXD input is considered a mark and if this bit is a
logic 1, a HIGH on the RXD input is considered a space.
RX1
55
I
RTS1#
60
O
UART channel 1 Request to Send or general purpose output (active low). If
this output is not used, leave it unconnected.
CTS1#
56
I
UART channel 1 Clear to Send or general purpose input (active low). This
input should be connected to VCC when not used.
DTR1#
61
O
UART channel 1 Data Terminal Ready or general purpose output (active
low). If this output is not used, leave it unconnected.
DSR1#
57
I
UART channel 1 Data Set Ready or general purpose input (active low). This
input should be connected to VCC when not used.
CD1#
58
I
UART channel 1 Carrier Detect or general purpose input (active low). This
input should be connected to VCC when not used.
RI1#
59
I
UART channel 1 Ring Indicator or general purpose input (active low). This
input should be connected to VCC when not used.
ANCILLARY SIGNALS
MPIO0-MPIO7
52-45
I/O
Multi-purpose inputs/outputs 0-7. The function of these pin are defined thru
the Configuration Register MPIOSEL, MPIOLVL, MPIOINV, MPIO3T and
MPIOINT
EECK
84
O
Serial clock to EEPROM. An internal clock of CLK divide by 256 is used for
reading the vendor and sub-vendor ID during power up or reset. However, it
can be manually clocked thru the Configuration Register REGB.
EECS
83
O
Chip select to a EEPROM device like 93C46. It is manually selectable thru
the Configuration Register REGB. Requires a pull-up 4.7K ohm resister for
external sensing of EEPROM during power up. See DAN112 for further
details.
EEDI
82
O
Write data to EEPROM device. It is manually accessible thru the Configura-
tion Register REGB. The D152 auto-configuration register interface logic
uses the 16-bit format.
EEDO
81
I
Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
XTAL1
77
I
Crystal of up to 24MHz or external clock input of up to 50MHz for data rates
up to 6.25Mbps at 5V and 8X sampling. See AC Characterization table. Cau-
tion: this input is not 5V tolerant at 3.3V.
XTAL2
76
O
Crystal or buffered clock output.
