TRMDn
Transfer Mode Specification
0
Single mode
1
Consecutive mode
DIRn
Transfer Direction Specification
0
MSB-first transfer
1
LSB-first transfer
Specifies the transfer direction when data is written from the SFDB3n register to the
CSIBUFn register or read from the SIRB3n and CSIBUFn registers.
CSITn
Transmission Completion Interrupt (INTC3n) Control
0
No delay
1
Delay mode (The interrupt request signal is delayed by half a cycle.)
Cautions: 1. The delay mode (CSIT bit = 1) is valid only in the master mode
(CKS3n2 to CKS3n0 bits of the CSIC3n register other than 111B). In
the slave mode (CKS3n2 to CKS3n0 bits = 111B), do not set the delay
mode. If the delay mode is set, INTC3n is not affected by the CSITn
bit.
2. If the CSITn bit is set to 1 in the consecutive mode (TRMDn bit = 1),
the INTC3n interrupt is not output except when the last data set by the
SFNn3 to SFNn0 bits of the SFN3n register is transferred, but a delay
of half a clock can be inserted between each data transferred.
CSWEn
Transfer Wait Control
0
Disables transfer wait.
1
Enables transfer wait (1 wait cycle inserted on starting transfer).
Caution:
Inserting a transfer wait cycle (CSWEn bit = 1) is valid only in the master
mode (CKS3n2 to CKS3n0 bits of the CSIC3n register other than 111B). In
the slave mode (CKS3n2 to CKS3n0 bits = 111B), do not insert a transfer
wait cycle. If set, a transfer wait cycle is not inserted.
CSMDn
Chip Select Mode Specification
0
Disables inactive level setting of chip select outputs (SCS3n0 to SCS3n3)
during transfer wait.
1
Enables inactive level setting of chip select outputs (SCS3n0 to SCS3n3)
during transfer wait.
Caution:
The CSMDn bit setting is valid only when the transfer wait is enabled
(CSWEn bit = 1) and the master mode is specified (CKS3n0 bits of the
CSIC3n register other than 111B).
In all other cases the CSMDn bit setting is invalid and no inactive level
setting of chip select outputs between two consecutive transfers takes
place.
