Section 19 Serial Communication Interface (SCI, IrDA, CRC)
19.3.6
SCR is a register that enables/disables the following SCI transfer operations and interrupt requests,
and selects the transfer clock source. For details on interrupt requests, see section 19.9, Interrupt
Sources. Some bits in SCR have different functions in normal mode and smart card interface
mode.
• When SMIF in SCMR = 0
• When SMIF in SCMR = 1

Description
Transmit Interrupt Enable
When this bit is set to 1, a TXI interrupt request is
enabled.
A TXI interrupt request can be cancelled by reading 1
from the TDRE flag and then clearing the flag to 0, or by
clearing the TIE bit to 0.
Receive Interrupt Enable
When this bit is set to 1, RXI and ERI interrupt requests
are enabled.
RXI and ERI interrupt requests can be cancelled by
reading 1 from the RDRF, FER, PER, or ORER flag and
then clearing the flag to 0, or by clearing the RIE bit to 0.
