Cautions 1. In the case of an SBF reception error, the mode returns to the SBF reception mode. The
Figure 15-10. Format of Asynchronous Serial Interface Control Register 6 (ASICL6) (2/2)
2. Before setting the SBRT6 bit, make sure that bit 7 (POWER6) and bit 5 (RXE6) of ASIM6 = 1.
3. The read value of the SBRT6 bit is always 0. SBRT6 is automatically cleared to 0 after SBF
4. Before setting the SBTT6 bit to 1, make sure that bit 7 (POWER6) and bit 6 (TXE6) of ASIM6 =
5. The read value of the SBTT6 bit is always 0. SBTT6 is automatically cleared to 0 at the end of
6. Do not set the SBRT6 bit to 1 during reception, and do not set the SBTT6 bit to 1 during
7. Before rewriting the DIR6 and TXDLV6 bits, clear the TXE6 and RXE6 bits to 0.

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).
