CSIBn control register 2 (CBnCTL2)
The CBnCTL2 register is an 8-bit register that controls the number of CSIB serial transfer bits.
This register can be read or written in 8-bit units.
Reset input clears this register to 00H.
Caution:
The CBnCTL2 register can be rewritten only when the CBnPWR bit of the CBnCTL0
register is 0 or when both the CB0TXE and CB0RXE bits are 0.
After reset:
