(4) CSIBn status register (CBnSTR)
CBnSTR is an 8-bit register that displays the CSIBn status.
This register can be read or written in 8-bit or 1-bit units, but the CBnTSF flag is read-only.
Reset sets this register to 00H.
In addition to reset input, the CBnSTR register can be initialized by clearing (0) the CBnCTL0.CBnPWR bit.

• Do not check the CBnOVE flag.
• Read this bit even if reading the reception data is not required.
