(3) CSIBn control register 2 (CBnCTL2)
CBnCTL2 is an 8-bit register that controls the number of CSIBn serial transfer bits.
This register can be read or written in 8-bit units.
Reset sets register to 00H.
Caution The CBnCTL2 register can be rewritten only when the CBnCTL0.CBnPWR bit = 0 or when
Remark
(n = 0 to 2)
CBnCTL2
both the CBnTXE and CBnRXE bits = 0.
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.
After reset: 00H
