Interrupt Operation
There are three interrupt sources in smart card interface mode: transmit data empty interrupt (TXI)
requests, transfer 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 15.8.
