Symbol

Function

RESET

Resets all internal registers. Initially must be HIGH to reset internal regis-

ters. When LOW, the TOIM3000 connects the UART with IrDA trans-

ceiver. Data received from the UART transmits out through the infrared

transmitter. Data received from the infrared receiver is routed to the

UART. When HIGH, the TOIM3000 connects the UART with the RS232

port. Data received from the UART transmits out through the RS232 port,

while data received from the RS232 port is routed to the UART. Minimum

hold time for reset is 1 ms.

RD_UART Received data to the UART

TD_UART Data fom the UART to be transmitted

B_CLK 16 times baud rate clock, input from the UART (Baudout)

XIN Oscillator input, 1.8432 MHz clock (to be connected to Xout pin of the

UART)

NC No connection

NC No connection

GND Ground in common with the UART and RS232 port

S0

Must be connected to GND

S1

RD_232

Must be connected to GND for output pulse length of 1.627 ms,

Connected to VCC for pulse length of 3/16 of bit *)

Data input from the RS232 port, RXD pin

TD_232 Data output to the RS232 port, TXD pin

NC No connection

TD_IR Data output to infrared transmitter TFDS3000

RD_IR Data receive input from the infrared transmitter TFDS3000

The use of a pulse length of 3/16 of bit duration is not recommended when both clocks, Xout and Baudout,

of the UART are available
