CSIBn control register 2 (CBnCTL2)
This is an 8-bit register that controls the number of serial transfer bits of CSIB.
It can be read or written in 8-bit units.
Reset input clears this register to 00H.

The CBnCTL2 register can be rewritten when the CBnPWR bit of the CBnCTL0 regis-
ter = 0 or when the CB0TXE and CB0RXE bits = 0.
n = 0, 1
If the number of transfer bits is not 8 or 16, prepare data, justifying it to the least sig-
nificant bit of the CBnTX or CBnRX register.
