Value
R/W Description
5 TEIE 0 R/W Transmit End Interrupt Enable
Enables or disables a transmit end interrupt (TEI)
request when there is no valid transmit data in TDR4
during transmission of MSB data. TEI can be cleared
by clearing the TEND flag in SCSR4 to 0 after the flag
is read as 1 or clearing this bit to 0.
0: Transmit end interrupt (TEI) request disabled
1: Transmit end interrupt (TEI) request enabled
4 SOL 0 R/W Extended Data
Sets the output level of the SO4 pin. When this bit is
read, the output level of the SO4 pin is read. The
output of the SO4 pin retains the value of the last bit of
transmit data after transmission is completed.
However, if this bit is changed before or after
transmission, the output level of the SO4 pin can be
changed. When the output level of the SO4 pin is
changed, the SOLP bit should be cleared to 0 and the
MOV instruction should be used. Note that this bit
should not be changed during transmission because
incorrect operation may occur.
[When reading]
0: The output level of the SO4 pin is low.
1: The output level of the SO4 pin is high.
[When writing]
0: The output level of the SO4 pin is changed to low.
1: The output level of the SO4 pin is changed to high.
3 SOLP 1 R/W SOL Write Protect
Controls change of the output level of the SO4 pin due
to the change of the SOL bit. When the output level of
the SO4 pin is changed, the setting of SOL = 1 and
SOLP = 0 or SOL = 0 and SOLP = 0 is made by the
MOV instruction. This bit is always read as 1.
0: When writing, the output level is changed according
to the value of the SOL pin.
1: When reading, this bit is always read as 1 and
cannot be modified.
