Section 13 Smart Card Interface
13.2.2
The function of SSR bit 4 is modified in smart card interface mode. This change also causes a
modification to the setting conditions for bit 2 (TEND).
Bits 7 to 5: These bits operate as in normal serial communication. For details see section 12.2.7,
Serial Status Register (SSR).
Bit 4—Error Signal Status (ERS): In smart card interface mode, this flag indicates the status of
the error signal sent from the receiving device to the transmitting device. The smart card interface
does not detection framing errors.

Serial Status Register (SSR)
Description
Indicates normal transmission, with no error signal returned
[Clearing conditions]
Indicates that the receiving device sent an error signal reporting a parity error
[Setting condition]
A low error signal was sampled.
The chip is reset, or enters standby mode or module stop mode
Software reads ERS while it is set to 1, then writes 0.
