15.2.3
Note: * When using the smart card interface, set bit 5 to 1.
The function of bits 7, 6, 3, and 2 of SMR changes in smart card interface mode.
Bit 7—GSM Mode (GM): Sets the smart card interface function to GSM mode.
This bit is cleared to 0 when the normal smart card interface is used. In GSM mode, this bit is set
to 1, the timing of setting of the TEND flag that indicates transmission completion is advanced,
and clock output control mode addition is performed. The contents of the clock output control
mode addition are specified by bits 1 and 0 of the serial control register (SCR).
