Cautions 1. In the case of an SBF reception error, return the mode to the SBF reception mode again and
hold (1) the status of the SBRF6 flag.
2. Before setting the SBRT6 bit to 1, make sure that bit 7 (POWER6) and bit 5 (RXE6) of ASIM6 =
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).
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. 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).
5. The read value of the SBTT6 bit is always 0. SBTT6 is automatically cleared to 0 at the end of
SBF transmission.
6. Before rewriting the DIR6 and TXDLV6 bits, clear the TXE6 and RXE6 bits to 0.
