14.2.3
Bit 7 of SMR has a different function in smart card interface mode. The related serial control
register (SCR) changes from bit 1 to bit 0.
Bit

Read/Write
Bit 7—GSM Mode (GM): Set at 0 when using the regular smart card interface. In GSM mode,
set to 1. When transmission is complete, initially the TEND flag set timing appears followed by
clock output restriction mode. Clock output restriction mode comprises serial control register bit 1
and bit 0.
Bits 6 to 0: Operate in the same way as for the normal SCI.
For details, see section 13.2.5, Serial Mode Register (SMR).
