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 disabled.
1: Transmit data empty interrupt request (TXI) is enabled.
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) and the overrun error interrupt request
(ERI) with the clocked synchronous format, when a
receive 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) and overrun
1: Receive data full interrupt request (RXI) and overrun
NACK Receive Interrupt Enable
This bit enables or disables the NACK receive interrupt
request (NAKI) and the overrun error (setting of the OVE
bit in ICSR) interrupt request (ERI) with the clocked
synchronous format, when the NACKF and AL bits in
ICSR are set to 1. NAKI can be canceled by clearing the
NACKF, OVE, or NAKIE bit to 0.
0: NACK receive interrupt request (NAKI) is disabled.
1: NACK receive interrupt request (NAKI) is enabled.
error interrupt request (ERI) with the clocked
synchronous format are disabled.
error interrupt request (ERI) with the clocked
synchronous format are enabled.
