Clocked serial interface mode registers 3n (CSIM3n)
The CSIM3n register controls the operation of CSI3n (n = 0, 1).
This registers can be read or written in 8-bit or 1-bit units.
Reset input sets this register to 00H.
Cautions: 1. Writing the TRMDn, DIRn, CSITn, CSWEn, and CSMDn bits is enabled only when
CTXEn bit = 0 and CRXEn bit = 0.
2. To use CSI3n, be sure to set the external pins related to the CSI3n function to
control the mode and set the CSIC3n register. Then set the CSICAEn bit to 1
before setting the other bits.

Supplies clock to CSI3n
Cautions: 1. The CSI3n unit is reset when the CSICAEn bit = 0, and CSI3n is
stopped. To operate CSI3n, first set the CSICAEn bit to 1.
2. When rewriting the CSICAEn bit from 0 to 1 or from 1 to 0,
simultaneously rewriting the bits other than the CSICAEn bit of the
CSIM3n register is prohibited.
When the CSICAEn bit = 0, rewriting the bits other than the CSICAEn
bit of the CSIM3n register, and the SFDB3n, SFDB3nL, and SFA3n
registers is prohibited.

Disables transmission
1
Enables transmission
Caution:
The CTXEn bit is reset when the CSICAEn bit is cleared to 0.
CRXEn
Reception Operation Enable
0
Disables reception
1
Enables reception
Caution:
The CRXEn bit is reset when the CSICAEn bit is cleared to 0.
