Cautions 1. In the case of an SBF reception error, the mode returns to the SBF reception mode. The
Figure 14-18. Format of Asynchronous Serial Interface Control Register 61 (ASICL61) (2/2)
2. Before setting the SBRT61 bit, make sure that bit 7 (POWER61) and bit 5 (RXE61) of ASIM61 =
3. The read value of the SBRT61 bit is always 0. SBRT61 is automatically cleared to 0 after SBF
4. Before setting the SBTT61 bit to 1, make sure that bit 7 (POWER61) and bit 6 (TXE61) of
5. The read value of the SBTT61 bit is always 0. SBTT61 is automatically cleared to 0 at the end
6. Do not set the SBRT61 bit to 1 during reception, and do not set the SBTT61 bit to 1 during
7. Before rewriting the DIR61 and TXDLV61 bits, clear the TXE61 and RXE61 bits to 0.
