(2) Clocked serial interface clock select register 3n (CSIC3n)
The CSIC3n register is an 8-bit register that controls the operation clock and operating mode of
CSI3n.
This register can be read or written in 8-bit or 1-bit units.
Reset input sets this register to 07H.
Caution: Data can be written to the CSIC3n register only when the CTXEn bit = 0 and CRXEn
bit = 0 in the CSIM3n register.
