Section 10 Serial Communication Interface
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.
SSB mode settings also become invalid. To control the level of the SO
ends, it is necessary to write to the SOL bit at the end of each transmission. Do not write to this
register while transmission is in progress, because that may cause a malfunction.
Bit 6: SOL
0
1
Bit 5 Overrun Error Flag (ORER): When an external clock is used, bit 5 indicates the
occurrence of an overrun error. If noise occurs during a transfer, causing an extraneous pulse to be
superimposed on the normal serial clock, incorrect data may be transferred. If a clock pulse is
input after transfer completion, this bit is set to 1 indicating an overrun.
Bit 5: ORER
0
1
Bits 4 to 2 Reserved Bits: Bits 4 to 2 are reserved. They are always read as 0, and cannot be
modified.
Bit 1 TAIL MARK Transmit Flag (MTRF): When bit MRKON is set to 1, bit 1 indicates that
TAIL MARK is being sent. Bit 1 is a read-only bit and cannot be modified.
Bit 1: MTRF
