(4) CSIFn status register (CFnSTR)
CFnSTR is an 8-bit register that displays the CSIFn status.
This register can be read or written in 8-bit or 1-bit units, but the CFnTSF flag is read-only.
Reset sets this register to 00H.
In addition to reset input, the CFnSTR register can be initialized by clearing (0) the CFnCTL0.CFnPWR bit.

When transfer ends, this flag is cleared to 0 at the last edge of the clock.
reading the value of the receive buffer, upon completion of the receive operation.
The CFnOVE flag displays the overrun error occurrence status in this case.
using transmission, note the following.
• Do not check the CFnOVE flag.
• Read this bit even if reading the reception data is not required.
