What ways to perform transmit/receive for V850/SF1 serial interface?

Latest Updated:03/26/2017


Is there any way to perform the transmit/receive completion for the V850/SF1 serial interface (UART)?


Mask the interrupt and check that bit 7 of STIC0 or STIC1 is set by the program.
If it is set, you can determine that the transmission is complete.
Regarding the reception, check CSIC1 or CSIC3.
In either case, if it is set, the transmission or reception is complete and so reset the flag using the program.
