(3) CSIBn control register 0 (CBnCTL0)
CBnCTL0 is an 8-bit register that controls CSIBn serial transfer.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 01H.
(n = 0 to 4)
CBnCTL0
After reset: 01H
Note These bits can only be rewritten when the CBnPWR bit is 0.
Caution To forcibly suspend transmission/reception, clear the CBnPWR
CBnPWR
CBnTXE
CBnRXE
CBnPWR
• The CBnPWR bit controls the CSIBn operation and resets the internal circuit.
• The SOBn output is low level when the CBnTXE bit is 0.
• When the CBnRXE bit is 0, no reception complete interrupt is output even when
the specified data is transferred, and the receive data (in the CBnRX register) is
not updated.

Note
However, the values of these bits can be changed to 0 or 1 at the
same time the CBnPWR bit is set.
