DESCRIPTION
O ^{UART channel 7 Request to Send or general purpose output (active LOW). See}
description of RTS0# pin.
I ^{UART channel 7 Clear to Send or general purpose input (active LOW). See descrip-}
tion of CTS0# pin.
O ^{UART channel 7 Data Terminal Ready or general purpose output (active LOW). See}
description of DTR0# pin.
I ^{UART channel 7 Data Set Ready or general purpose input (active LOW). See}
description of DSR0# pin.
I ^{UART channel 7 Carrier Detect or general purpose input (active LOW).}
I ^{UART channel 7 Ring Indicator or general purpose input (active LOW).}
I ^{Crystal or external clock input.}
O ^{Crystal or buffered clock output.}
I ^{16-bit timer/counter external clock input.}
I ^{Infrared mode enable (active HIGH). This pin is sampled during power up, following}
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 transferred to MCR bit-6 in
the UART.
I ^{Reset (active LOW). The XR16M598 does not have a Power-on reset. Therefore, a}
hardware reset must be issued using this pin during power-up. The configuration
and UART registers are reset to default values, see Table 19.
I ^{Intel or Motorola data bus interface select. The Intel bus interface is selected when}
this input is HIGH and the Motorola bus interface is selected when this input is LOW.
This input affects the functionality of IOR#, IOW# and CS# pins.
+1.62V to 3.63V supply voltage.
Power supply common, ground.
NOTE: Pin type: I=Input, O=Output, IO= Input/output, OD=Output Open Drain.
