OXFORD SEMICONDUCTOR LTD.  
Additional status:  
Device ID:  
Software drivers are able to read the status of in-band and  
out-of-band automatic flow control, and distinguish  
between Xoff and special character received interrupts.  
Four bytes of device ID are available to identify the  
OX16C950 device to software drivers.  
Infra-red ‘IrDA’ interface:  
Software reset:  
The UART contains an IrDA compliant modulator and  
The software driver may reset the device to recover from  
demodulator.  
unforeseen or unusual error conditions.  
9-bit data framing:  
Transmitter empty interrupt:  
The transmitter can generate an interrupt when the FIFO  
and shift register are both empty.  
The OX16C950 may be configured to use in 9-bit character  
framing for multi-drop protocols where a tag ID (9th bit)  
differentiates address and data characters.  
RS485 buffer enable:  
The DTR# pin may be re-assigned as a buffer-enable  
signal for RS485 line driver in half-duplex mode (see  
ACR[4:3] in section 15.3).
