(4) CSIB0 status register (CB0STR)
CB0STR is an 8-bit register that displays the CSIB0 status.
This register can be read or written in 8-bit or 1-bit units, but the CB0TSF flag is read-only.
Reset sets this register to 00H.
In addition to reset, the CB0STR register can be initialized by clearing (0) the CB0CTL0.CB0PWR bit.
CB0STR
After reset: 00H
Caution In single transfer mode, writing to the CB0TX register with the CB0TSF
CB0OVE
• An overrun error occurs when the next reception starts without performing a CPU
• The CB0OVE flag is cleared by writing 0 to it. It cannot be set even by writing 1 to it.
CB0TSF
• During transmission, this register is set when data is prepared in the CB0TX
CB0TSF
read of the value of the CB0RX register, upon end of the receive operation.
The CB0OVE flag displays the overrun error occurrence status in this case.
register, and during reception, it is set when a dummy read of the CB0RX register
is performed.
When transfer ends, this flag is cleared to 0 at the last edge of the clock.
