17.5.7 Slave
mode
The slave mode is set when the CKS3n2 to CKS3n0 bits of the CSIC3n register are set to 111B, and
data is transferred with the transfer clock input to the SCK3n pin (in the slave mode, it is recommended
to set the MDLn2 to MDLn0 bits of the CSIC3n register to 000B and set the BRGn stop mode)
(n = 0, 1).
The chip select outputs (SCS3n0 to SCS3n3) are ineffective in slave mode, the output levels are fixed
to inactive level (chip select outputs are effective in master mode only).
Figure 17-17:
Slave Mode
CKPn and DAPn Bits of CSIC3n Register = 00B,
Active Level of CS Outputs: Low Level (CSLVn3 to CSLVn0 Bits of CSIL3n Register = 0000B)
Transfer Data Length: 8 Bits (CCLn3 to CCLn0 Bits of CSIL3n Register = 1000B)
The conditions under which data can be transferred in the slave mode are listed in the table below.
Remarks: 1.
CTXEn bit:
Bit 6 of CSIM3n register
CRXEn bit:
Bit 5 of CSIM3n register
SFEMPn bit:
