Interrupts
Table 74.
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).
SCI synchronous transmission
The SCI transmitter allows the user to control a one way synchronous serial transmission.
The SCLK pin is the output of the SCI transmitter clock. No clock pulses are sent to the
SCLK pin during start bit and stop bit. Depending on the state of the LBCL bit in the SCICR3
register, clock pulses are or are not be generated during the last valid data bit (address
mark). The CPOL bit in the SCICR3 register allows the user to select the clock polarity, and
the CPHA bit in the SCICR3 register allows the user to select the phase of the external clock
(see
During idle, preamble and send break, the external SCLK clock is not activated.
These options allow the user to serially control peripherals which consist of shift registers,
without losing any functions of the SCI transmitter which can still talk to other SCI receivers.
These options do not affect the SCI receiver which is independent from the transmitter.

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.
