23. Serial Communications Interface (SCIg, SCIh)
(2) Smart Card Interface Mode (SCMR.SMIF = 1)
x: Don’t care
Note 1. Writable only when TE = 0 and RE = 0.
Note 2. 1 can be written only when TE = 0 and RE = 0. After setting TE or RE to 1, only 0 can be written in TE and RE.
For details on interrupt requests, refer to
section 23.12, Interrupt Sources
These bits control the clock output from the SCKn pin.
In GSM mode, clock output can be dynamically switched. For details, refer to
section 23.6.8, Clock Output Control
TEIE Bit (Transmit End Interrupt Enable)
This bit should be 0 in smart card interface mode.
MPIE Bit (Multi-Processor Interrupt Enable)
This bit should be 0 in smart card interface mode.
