Bit Bit Name
Initial
Value R/W Description
3 TEND 0 R/W Transmit End
[Setting condition]
• When the last bit of data is transmitted, the TDRE bit
is 1
[Clearing conditions]
• When 0 is written to this bit after reading 1
• When data is written in SSTDR
2 TDRE 1 R/W Transmit Data Empty
[Setting conditions]
• When the TE bit in SSER is 0
• When data transfer is performed from SSTDR to
SSTRSR and data can be written in SSTDR
[Clearing conditions]
• When 0 is written to this bit after reading 1
• When data is written in SSTDR
1 RDRF 0 R/W Receive Data Register Full
[Setting condition]
• When serial reception is completed normally and
receive data is transferred from SSTRSR to SSRDR
[Clearing conditions]
• When 0 is written to this bit after reading 1
• When data is read from SSRDR
0 CE 0 R/W Conflict Error Flag
[Setting conditions]
• When serial communication is started while SSUMS =
1 and MSS =1, the SCS pin input is low
• When the SCS pin level changes from low to high
during transfer while SSUMS = 1 and MSS = 0
[Clearing condition]
• When 0 is written to this bit after reading 1
