Bit 4: SOL

Bit 3—Overrun Error Flag (ORER): When an external clock is used, bit 3 indicates the
occurrence of an overrun error. If a clock pulse is input after transfer completion, this bit is set to 1
indicating an overrun. If noise occurs during a transfer, causing an extraneous pulse to be
superimposed on the normal serial clock, incorrect data may be transferred. Overrun errors are not
detected while pin CS is at the high level.
Bit 3: ORER
0
1
Bit 2—Wait Flag (WT): Bit 2 indicates that an attempt was made to read or write the 32-byte
serial data buffer while a transfer was in progress, or while waiting for CS input. The read or write
access is not carried out, and this bit is set to 1.
Bit 2: WT
0
1
Bit 1—Abort Flag (ABT): Bit 1 indicates that CS went to high during data transfer. When the CS
input function is selected, if a high-level signal is detected at pin CS during a transfer, the transfer
is immediately aborted and this bit is set to 1. At the same time bit IRRS2 in interrupt request
register 2 (IRR2) is set
to 1, and pins SCK
buffer and values in the internal registers other than SCSR2 remain unchanged.
Transfer cannot take place while this bit is set to 1. It must be cleared to 0 before resuming the
transfer.
