Interrupts
The SCI interrupt events are connected to the same interrupt vector.
These events generate an interrupt if the corresponding Enable Control bit is set and the
interrupt mask in the CC register is reset (RIM instruction).

Interrupt event
No effect on SCI.
SCI interrupts cause the device to exit from Wait mode.
SCI registers are frozen.
In Halt mode, the SCI stops transmitting/receiving until Halt mode is exited.

SCISR register description
Transmit Data Register Empty
This bit is set by hardware when the content of the TDR register has been transferred
into the shift register. An interrupt is generated if the TIE bit = 1 in the SCICR2
register. It is cleared by a software sequence (an access to the SCISR register
followed by a write to the SCIDR register).
0: Data is not transferred to the shift register.
1: Data is transferred to the shift register.
Note: Data will not be transferred to the shift register unless the TDRE bit is cleared.
