SSR—Serial Status Register
636
Note: * Software can write a 0 in bits 7 to 3 to clear the flags, but cannot write a 1 in these bits.
Bit
Initial value
Read/Write
Transmit Data Register Empty
0
1
Cleared by reading TDRE = 1, then writing 0 in TDRE.
Set when:
1. Data is transferred from TDR to TSR.
2. TE is cleared while TDRE = 0.
Receive Data Register Full
0
1
Cleared by reading RDRF = 1, then writing 0 in RDRF.
Set when one character is received normally and transferred from RSR to RDR.
Overrun Error
TDRE
0
1
R/(W)
7
1
Cleared by reading ORER = 1, then writing 0 in ORER.
Set when an overrun error occurs (next data is completely
received while RDRF bit is set to 1).
*
Framing Error
0
1
RDRF
R/(W)
Cleared by reading FER = 1, then writing 0 in FER.
Set when a framing error occurs (stop bit is 0).
6
0
Parity Error
0
1
*
Cleared by reading PER = 1, then writing 0 in PER.
Set when a parity error occurs (parity of receive data
does not match parity selected by O/E bit in SMR).
ORER
R/(W)
5
0
Transmit End
0
1
*
Cleared by reading TDRE = 1, then writing 0 in TDRE.
Set to 1 when TE = 0, or when TDRE = 1 at the end of
character transmission.
