CBnCTL2 - CSIBn control register 2
CBnCTL2 is an 8-bit register that controls the number of CSIBn serial transfer
bits.
This register can be read/written in 8-bit units.
<base> + 2
00
The CBnCTL2 register can be rewritten only when the
CBnCTL0.CBnPWR bit = 0 or when both the CBnTXE and CBnRXE bits = 0.
CBnCTL2 register contents
If the number of transfer bits is other than 8 or 16, prepare and use data stuffed
from the LSB of the CBnTX and CBnRX registers.
