Register description
Status register (SCISR)
Read only
Reset value: 1100 0000 (C0h)
Bit 7 = TDRE Transmit data register empty.
This bit is set by hardware when the content of the TDR register has been transferred into
the shift register. An interrupt is generated if the TIE bit = 1 in the SCICR2 register. It is
cleared by a software sequence (an access to the SCISR register followed by a write to the
SCIDR register).
Data is not be transferred to the shift register until the TDRE bit is cleared.
Bit 6 = TC Transmission complete.
This bit is set by hardware when transmission of a frame containing Data is complete. An
interrupt is generated if TCIE = 1 in the SCICR2 register. It is cleared by a software
sequence (an access to the SCISR register followed by a write to the SCIDR register).
TC is not set after the transmission of a Preamble or a Break.
Bit 5 = RDRF Received data ready flag.
This bit is set by hardware when the content of the RDR register has been transferred to the
SCIDR register. An interrupt is generated if RIE = 1 in the SCICR2 register. It is cleared by a
TDRE
0: data is not transferred to the shift register
1: data is transferred to the shift register
0: transmission is not complete
