Chip select to a EEPROM device like 93C46. It is manually selectable thru the
Configuration Register REGB. Requires a pull-up 4.7K ohm resistor 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.
Read data from EEPROM device. It is manually accessible thru the Configu-
ration Register REGB.
Crystal or external clock input.
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 8 UARTs in the infrared mode. The sampled logic state is trans-
ferred to MCR bit-6 in the UART.
Factory Test. Connect to VCC for normal operation.
+5V power supply. For a pin-to-pin compatible device that operates at 3.3V,
see the XR17D158.
Power supply common, ground.
