Name:
Access Type:
Reset Value:
Offset:
• RXRDY: Receiver Ready (Code Label US_RXRDY)
0 = No complete character has been received since the last read of the US_RHR or the receiver is disabled.
1 = At least one complete character has been received and the US_RHR has not yet been read.
• TXRDY: Transmitter Ready (Code Label US_TXRDY)
0 = US_THR contains a character waiting to be transferred to the Transmit Shift Register, or an STTBRK command has
been requested.
1 = US_THR is empty and there is no Break request pending TSR availability.
Equal to zero when the USART is disabled or at reset. Transmitter Enable command (in US_CR) sets this bit to one.
• RXBRK: Break Received/End of Break (Code Label US_RXBRK)
0 = No Break Received nor End of Break has been detected since the last “Reset Status Bits” command in the Control
Register.
1 = Break Received or End of Break has been detected since the last “Reset Status Bits” command in the Control Register.
• ENDRX: End of Receiver Transfer (Code Label US_ENDRX)
0 = The End of Transfer signal from the Peripheral Data Controller channel dedicated to the receiver is inactive.
1 = The End of Transfer signal from the Peripheral Data Controller channel dedicated to the receiver is active.
• ENDTX: End of Transmitter Transfer (Code Label US_ENDTX)
0 = The End of Transfer signal from the Peripheral Data Controller channel dedicated to the transmitter is inactive.
1 = The End of Transfer signal from the Peripheral Data Controller channel dedicated to the transmitter is active.
• OVRE: Overrun Error (Code Label US_OVRE)
0 = No byte has been transferred from the Receive Shift Register to the US_RHR when RxRDY was asserted since the last
“Reset Status Bits” command.
1 = At least one byte has been transferred from the Receive Shift Register to the US_RHR when RxRDY was asserted
since the last “Reset Status Bits” command.
• FRAME: Framing Error (Code Label US_FRAME)
0 = No stop bit has been detected low since the last “Reset Status Bits” command.
1 = At least one stop bit has been detected low since the last “Reset Status Bits” command.
