1 0 1 SBF is output with 13-bit length.
1 1 0 SBF is output with 14-bit length.
1 1 1 SBF is output with 15-bit length.
0 0 0 SBF is output with 16-bit length.

DIR6 First-bit specification
0 MSB
1 LSB
TXDLV6 Enables/disables inverting TXD6 output
0 Normal output of TXD6
1 Inverted output of TXD6
Cautions 1. In the case of an SBF reception error, the mode returns to the SBF reception mode. The status of
the SBRF6 flag is held (1).
2. Before setting the SBRT6 bit, make sure that bit 7 (POWER6) and bit 5 (RXE6) of ASIM6 = 1. After
setting the SBRT6 bit to 1, do not clear it to 0 before SBF reception is completed (before an
interrupt request signal is generated).
3. The read value of the SBRT6 bit is always 0. SBRT6 is automatically cleared to 0 after SBF
reception has been correctly completed.
4. Before setting the SBTT6 bit to 1, make sure that bit 7 (POWER6) and bit 6 (TXE6) of ASIM6 = 1.
After setting the SBTT6 bit to 1, do not clear it to 0 before SBF transmission is completed (before
an interrupt request signal is generated).
5. The read value of the SBTT6 bit is always 0. SBTT6 is automatically cleared to 0 at the end of
SBF transmission.
6. Do not set the SBRT6 bit to 1 during reception, and do not set the SBTT6 bit to 1 during
transmission.
7. Before rewriting the DIR6 and TXDLV6 bits, clear the TXE6 and RXE6 bits to 0.
8. When the TXDLV6 bit is set to 1 (inverted TxD6 output), the TxD6/SCLA0/P60 pin cannot be used
as a general-purpose port, regardless of the settings of POWER6 and TXE6. When using the
TxD6/SCLA0/P60 pin as a general-purpose port, clear the TXDLV6 bit to 0 (normal TxD6 output).
