Serial Control/Status Register 1 (SCSR1)
Note: * Only a write of 0 for flag clearing is possible.
SCSR1 is an 8-bit read/write register indicating operation status and error status.
Upon reset, SCSR1 is initialized to H'80.
Bit 7—Reserved Bit: Bit 7 is reserved; it is always read as 1, and cannot be modified.
Bit 6—Extended Data Bit (SOL): Bit 6 sets the SO
output level at the SO
of the last bit of transmitted data. The SO
after a transmission. The SOL bit setting remains valid only until the start of the next transmission.
To control the level of the SO
the end of each transmission. Do not write to this register while transmission is in progress,
because that may cause a malfunction.

Bit 5—Overrun Error Flag (ORER): When an external clock is used, bit 5 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.
