Preliminary Data Sheet  
Universal Asynchronous Receiver/Transmitter  
Name  
RI_n  
Type  
Description  
I
Ring Indicator - Active Low - Active state indicates that the ring  
signal has been detected by the MODEM or data set. A change  
in state of this input is recorded in the TERI bit (bit 2) of the  
MODEM Status register. Whenever DSR_n changes state, an  
interrupt is generated if the MODEM Status interrupt is  
enabled. The complement of this input is recorded in the RI  
(bit 6) bit of the MODEM Status register  
DOUT(7:0)  
DDIS  
O
O
Data Output Bus - Active high - Serves as output data when  
reading from internal UART registers.  
Driver Disable - Active High - Active State indicates that the  
CPU is reading data from the UART. This output is intended as  
a disable or direction control between the UART and CPU.  
CSOUT  
O
Chip Select Output - Active High - Active State indicates that  
the megafunction has been selected by use of the CS0, CS1 and  
CS2_n inputs.  
SOUT  
O
O
Serial Data Out - Active High - Serial (transmit) data out. This  
signal is set to the marking (logic 1) state upon master reset.  
BAUDOUT_n  
Baud Out - Active Low - The 16x baud rate clock used by the  
transmitter section of the UART. This output is controlled by  
the programmable baud rate generator.  
RTS_n  
O
O
Request to Send - Active Low - This output indicates that the  
UART is ready to exchange data. This output is controlled by  
writing to the RTS (bit 1) bit of the control register.  
DTR_n  
Data Terminal Ready - Active Low - This output indicates that  
the UART is ready to establish a communications link. This  
output is controlled by writing to the DTR (bit 0) bit of the  
control register.  
OUT1_n  
OUT2_n  
INTR  
O
O
O
Discrete Output - Active Low - One of two user-programmable  
discrete outputs. This output is controlled by writing to the  
OUT1 (bit 2) bit of the control register.  
Discrete Output - Active Low - One of two user-programmable  
discrete outputs. This output is controlled by writing to the  
OUT2 (bit 3) bit of the control register.  
Interrupt - Active High - Indicates that an enabled interrupt has  
had its interrupt condition met.
