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.
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 exter-
nal sensing of EEPROM during power up. See DAN112 for further details.
Write data to EEPROM device. It is manually accessible thru the Configura-
tion Register REGB. The 154 auto-configuration register interface logic uses
the 16-bit format.
Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
Crystal or external clock input of up to 50MHz for data rate of 3.125Mbps at
5V.
Crystal or buffered clock output.
16-bit timer/counter external clock input.
Infrared mode enable (active high). This pin is sampled during power up, fol-
lowing a hardware reset (RST#) or soft-reset (register RESET). It can be used
to start up all 4 UARTs in the infrared mode. The sampled logic state is trans-
ferred to MCR bit-6 in the UART. Software can override this pin thereafter
and enable or disable it.
Factory Test. Connect to VCC for normal operation.
+5V (PCI Compliance). For 3.3V operation, see the XR17D154.
