2. A 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.
SCR is a register that enables/disables the SCI transfer operations and selects the transfer clock source. For details on
interrupt requests, see 20.6, Interrupt Sources.
CKE[1:0] Bits (Clock Enable)
These bits control the clock output from the SCKn pin.
In GSM mode, clock output can be dynamically switched. For details, see section 20.5.8, Clock Output Control.
TEIE Bit (Transmit End Interrupt Enable)
This bit should be 0 in smart card interface mode.
