Interrupt Operation (Except Block Transfer Mode): There are three interrupt sources in smart
card interface mode: transmit-data-empty interrupt (TXI) requests, transmit/receive-error interrupt
(ERI) requests, and receive-data-full interrupt (RXI) requests. The transmit-end interrupt (TEI)
request is not used in this mode.
When the TEND flag in SSR is set to 1, a TXI interrupt request is generated.
When the RDRF flag in SSR is set to 1, an RXI interrupt request is generated.
When any of flags ORER, PER, and ERS in SSR is set to 1, an ERI interrupt request is generated.
The relationship between the operating states and interrupt sources is shown in table 13.8.
Note: For details of operation in block transfer mode, see section 12.4, SCI Interrupts.
