Description
Transmit Interrupt Enable
When the TDRE bit in ICSR is set to 1, this bit
enables or disables the transmit data empty
interrupt (TXI).
0: Transmit data empty interrupt request (TXI) is
1: Transmit data empty interrupt request (TXI) is
Transmit End Interrupt Enable
This bit enables or disables the transmit end
interrupt (TEI) at the rising of the ninth clock while
the TDRE bit in ICSR is 1. TEI can be canceled by
clearing the TEND bit or the TEIE bit to 0.
0: Transmit end interrupt request (TEI) is disabled.
1: Transmit end interrupt request (TEI) is enabled.
Receive Interrupt Enable
This bit enables or disables the receive data full
interrupt request (RXI) when a received data is
transferred from ICDRS to ICDRR and the RDRF
bit in ICSR is set to 1. RXI can be canceled by
clearing the RDRF or RIE bit to 0.
0: Receive data full interrupt request (RXI) is
1: Receive data full interrupt request (RXI) is
disabled.
