66MHZ PCI BUS OCTAL UART WITH POWER MANAGEMENT SUPPORT
NOTE: Pin type: I=Input, O=Output, IO= Input/output, OD=Output Open Drain.
TMRCK
69
I
16-bit timer/counter external clock input.
ENIR
70
I
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
transferred to MCR bit [6] in the UART.
VCC
64, 90,112, 4,
19, 34, 45, 137
Power supply for the UART core logic and PCI bus I/O - 3.3V only. The V258
is PCI 3.0 signalling compliant at 3.3V operation. The non-PCI inputs (except
XTAL1) are 5V tolerant. This includes all the serial (modem) inputs.
GND
5,20,35,46,63,
89,136
Power supply common, ground.
