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.
