Z8 Encore! XP® 4K Series  
Product Specification  
102  
0 = No parity error has occurred.  
1 = A parity error has occurred.  
OE—Overrun Error  
This bit indicates that an overrun error has occurred. An overrun occurs when new data is  
received and the UART Receive Data register has not been read. If the RDA bit is reset to  
0, reading the UART Receive Data register clears this bit.  
0 = No overrun error occurred.  
1 = An overrun error occurred.  
FE—Framing Error  
This bit indicates that a framing error (no Stop bit following data reception) was detected.  
Reading the UART Receive Data register clears this bit.  
0 = No framing error occurred.  
1 = A framing error occurred.  
BRKD—Break Detect  
This bit indicates that a break occurred. If the data bits, parity/multiprocessor bit, and Stop  
bit(s) are all 0s this bit is set to 1. Reading the UART Receive Data register clears this bit.  
0 = No break occurred.  
1 = A break occurred.  
TDRE—Transmitter Data Register Empty  
This bit indicates that the UART Transmit Data register is empty and ready for additional  
data. Writing to the UART Transmit Data register resets this bit.  
0 = Do not write to the UART Transmit Data register.  
1 = The UART Transmit Data register is ready to receive an additional byte to be transmit-  
ted.  
TXE—Transmitter Empty  
This bit indicates that the transmit shift register is empty and character transmission is fin-  
ished.  
0 = Data is currently transmitting.  
1 = Transmission is complete.  
CTS—CTS signal  
When this bit is read it returns the level of the CTS signal. This signal is active Low.
