Cautions 1. In the case of an SBF reception error, return to SBF reception mode again. The status of the
Figure 11-10. Format of Asynchronous Serial Interface Control Register 6 (ASICL6) (2/2)
2. Before setting the SBRT6 bit to 1, make sure that bit 7 (POWER6) and bit 5 (RXE6) of ASIM6 =
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.

SBRF6 flag will be held (1). For details on SBF reception refer to (2) – (i) SBF reception in
11.4.2 Asynchronous serial interface (UART) mode described later.
1. Moreover, after setting the SBRT6 bit to 1, do not clear the SBRT6 bit to 0 before the SBF
reception ends (an interrupt request signal is generated).
reception has been correctly completed.
1. Moreover, after setting the SBTT6 bit to 1, do not clear the SBTT6 bit to 0 before the SBF
transmission ends (an interrupt request signal is generated).
