Transfer data length select register 3n (CSIL3n)
The CSIL3n register is used to select the transfer data length of CSI3n.
This register can be read or written in 8-bit or 1-bit units.
Reset input clears the register to 00H.
Caution:
The CSIL3n register may be transferring data when the CTXEn or CRXEn bit of the
CSIM3n register is 1. Before writing data to the CSIL3n register, be sure to clear the
CTXEn and CRXEn bits to 0.

Caution:
If a transfer data length other than 16 bits is specified (CCLn3 to CCLn0
bits = 0000), an undefined value is read to the higher excess bits of the
SIRB3n and CSIBUFn registers (see 10.3.5 (3) Data transfer direction
specification function).
