(6) 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.
(n = 0 to 4)

• An overrun error occurs when the next reception is completed without the CPU
• The CBnOVE bit is valid also in the single transfer mode. Therefore, when only
• The CBnOVE flag is cleared by writing 0 to it. It cannot be set even by writing 1 to it.
• During transmission, this register is set when data is prepared in the CBnTX

register, and during reception, it is set when a dummy read of the CBnRX register
is performed.
When transfer ends, this flag is cleared to 0 at the last edge of the clock cycle.
reading the value of the receive buffer, during reception or upon completion of a
receive operation.
The CBnOVE flag displays the overrun error occurrence status in this case.
using transmission, note the following.
• Do not check the CBnOVE flag.
• Read this bit even if reading the receive data is not required.
