Bit 6—Receive Data Register Full (RDRF): Indicates that RDR contains received data.
Bit 5—Overrun Error (ORER): Indicates that data reception ended abnormally due to an
overrun error.
bit to 0 in the serial control register. They retain their previous contents. If RDRF is still set
to 1 when reception of the next data ends, an overrun error (ORER) occurs and the
received data is lost.
Description
RDR does not contain valid received data (initial value)
RDRF is cleared to 0 when the chip is power-on reset, software reads RDRF
after it has been set to 1, then writes 0 in RDRF
RDR contains valid received data
RDRF is set to 1 when serial data is received normally and transferred from RSR
to RDR
Description
Receiving is in progress or has ended normally (initial value). Clearing the RE bit
to 0 in the serial control register does not affect the ORER bit, which retains its
previous value.
ORER is cleared to 0 when the chip is power-on reset or software reads ORER
after it has been set to 1, then writes 0 in ORER
A receive overrun error occurred. RDR continues to hold the data received
before the overrun error, so subsequent receive data is lost. Serial receiving
cannot continue while ORER is set to 1.
ORER is set to 1 if reception of the next serial data ends when RDRF is set to 1
