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

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
16 times baud rate clock, input from the UART (Baudout)
Oscillator input, 1.8432 MHz clock (to be connected to Xout pin of the
UART)
No connection
