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
