Cautions 1. In the case of an SBF reception error, the mode returns to the SBF reception mode. The
Figure 14-17. Format of Asynchronous Serial Interface Control Register 60 (ASICL60) (2/2)
2. Before setting the SBRT60 bit, make sure that bit 7 (POWER60) and bit 5 (RXE60) of ASIM60 =
3. The read value of the SBRT60 bit is always 0. SBRT60 is automatically cleared to 0 after SBF
4. Before setting the SBTT60 bit to 1, make sure that bit 7 (POWER60) and bit 6 (TXE60) of
5. The read value of the SBTT60 bit is always 0. SBTT60 is automatically cleared to 0 at the end
6. Do not set the SBRT60 bit to 1 during reception, and do not set the SBTT60 bit to 1 during
7. Before rewriting the DIR60 and TXDLV60 bits, clear the TXE60 and RXE60 bits to 0.
