15. Serial Communication Interface (SCI)
• In reception, note that if RE is cleared to 0 from 2.5 to 3.5 peripheral operating clock cycles
When Using Synchronous Internal Clock Mode: In reception, note that if RE is cleared to zero
1.5 peripheral operating clock cycles after the rising edge of the RxD D7 bit SCK output, RDRF
will be set to 1 but copying to SCRDR1 will not be possible.
When Using DMAC: When using the DMAC for transmission/reception, make a setting to
suppress output of RXI and TXI interrupt requests to the interrupt controller. Even if a setting is
made to output interrupt requests, interrupt requests to the interrupt controller will be cleared by
the DMAC independently of the interrupt handling program.
