Cautions 1. In the case of an SBF reception error, the mode returns to the SBF reception mode. The
Figure 13-10. 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. 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).
