Notes:
2. If TXD is stuck in the high state, the LED will turn off after about 14
μ
s.
3. RXD will echo the TXD signal while TXD is transmtting data.
4. In-Band IrDA signals and data rates
1.152 Mbps.
5. RXD Logic Low is pulsed response.
6. RXD Logic High during shutdown is a weak pull up (equivalent to an approximately 300 k
resistor).
