X: do not care
S1, S2: user programmable bit to program the outputs S1
and S2
S0: IrDA pulse select
S0 = (1): 1.627 μs output pulses
S0 = (0): 3/16 bit time pulses, not recommended
B0 to B3: baud rate select words according following table.
Example:
To set TOIM5232 at COM2 port (2F8) to 9600 bit/s with
3/16 bit time pulse duration send to the TOIM5232 in
programming mode in e.g. “basic”
OUT &H2F8, (&H6)
For same port, 9600 bit/s and 1.627 μs pulse duration send
OUT &H2F8, (&H16)
For additionally activating S1 send
OUT &H2F8, (&H36)
Note
IrDA standard only supports 2.4 kbit/s, 9.6 kbit/s, 19.2 kbit/s,
57.6 kbit/s, and 115.2 kbit/s (3.6864 MHz clock). Doubling the baud
rates is allowed by doubling the clock frequency.
SOFTWARE FOR THE TOIM4232 AND TOIM5232 UART PROGRAMMING
For proper operation, the RS232 must be programmed (using 8 bit, 1 stop, no parity) to send a two character control word, YZ.
The control word YZ is composed of two characters, written in hexadecimal, in format: YZ. The transfer rate for programming
must be identical with the formerly programmed data rate, or after resetting the TOIM5232, the default rate of 9600 bit/s is used.
Note
It is recommended reading the I/O buffer after transmission waiting the specified latency allowance. That avoids receiving unexpected data
from pulses stochastically generated by many transceivers during the latency time.
(1) For programming the UART, refer to e.g., National Semiconductors datasheet of PC 16550 UART.

DESCRIPTION AND COMMENTS

Resets all internal registers. Resets to
IrDA default data rate of 9600 bit/s
2Low
X
Wait at least 2 ms, to allow start-up of
internal clock. When external clock is
used: wait at least 7 μs.
3Low

Wait at least 7 μs. TOIM5232 now is set to

XX
X
Sending the control word YZ.
Examples: Send “1Z” if 1.627 μs pulses
are intended to be used. Otherwise send
“0Z” for 3/16 bit period pulses. “Y6”
keeps the 9.6 kbit/s data rate. Z = 0 sets
to 115.2 kbit/s, see programming table.
Wait at least 1 μs for hold-time.

Low
Data
With BR/D = 0, TOIM5232 is in the data
communication mode. Both RESET and
BR/D must be kept low (“0”) during data
transmission. Reprogramming to a new
data rate can be resumed by restarting
from step 3. The UART itself also must set
to the correct data rate (1).
