C-bus Interface (RIICa)
TEIE Bit (Transmit End Interrupt Request Enable)
This bit is used to enable or disable transmit end interrupt (TEI) requests when the ICSR2.TEND flag is set to 1. An TEI
interrupt request is canceled by setting the TEND flag or the TEIE bit to 0.
TIE Bit (Transmit Data Empty Interrupt Request Enable)
This bit is used to enable or disable transmit data empty interrupt (TXI) requests when the ICSR2.TDRE flag is set to 1.
