CSIBUF Status Register 3n (SFA3n)(2/3)

SFFULn
CSIBUFn Full Status Flag
0
CSIBUFn register has a vacancy
1
CSIBUFn is full
Cautions: 1. This bit is cleared to 0 when the CSICAEn bit of the CSIM3n register
is cleared to 0 and the FPCLR bit is set to 1.
2. If transfer of 16 data is specified in the consecutive mode (TRMDn bit
of the CSIM3n register = 1) (SFNn3 to SFNn0 bits of the SFN3n
register = 0000B), the SFFULn bit is set to 1 in the same way as in the
single mode (TRMDn bit of the CSIM3n register = 0) when 16 data are
in the CSIBUFn register. If even one of the data has been completely
transferred, the SFFULn bit is cleared to 0. However, this does not
mean that the CSIBUFn register has a vacancy.
SFEMPn
CSIBUFn Empty Status Flag
0
Data is in CSIBUFn register
1
CSIBUFn is empty
Cautions: 1. This flag is cleared to 0 when the CSICAEn bit of the CSIM3n register
is cleared to 0 and the FPCLR bit is set to 1.
2. If the data written to the CSIBUFn register has been transferred in the
consecutive mode (TRMDn bit of the CSIM3n register = 1), the SFEMP
bit is set to 1 in the same way as in the single mode (TRMDn bit of the
CSIM3n register = 0) even if receive data is stored in the CSIBUF
register.
CSOTn
Transfer Status Flag
0
Idle status
1
Transfer or transfer start processing in progress
Cautions: 1. This flag is cleared to 0 when the CSICAEn bit of the CSIM3n register
is cleared to 0 and the FPCLRn bit is set to 1, or when the CTXEn and
CRXEn bits of the CSIM3n register are cleared to 0.
2. This flag is set (1) from when transfer is started until there is no more
transfer data in the CSIBUFn register in the single mode (TRMDn bit
of the CSIM3n register = 0) or until the specified number of data has
been transferred in the consecutive mode (TRMDn bit of the CSIM3n
register = 1).
