Mode

Description

No effect on SCI.

Wait

SCI interrupts cause the device to exit from Wait mode.

SCI registers are frozen.

Halt

In Halt mode, the SCI stops transmitting/receiving until Halt mode is exited.

10.5.6 Interrupts

) The SCI interrupt events are connected to the same interrupt vector.

t(s These events generate an interrupt if the corresponding Enable Control bit is set and the

c interrupt mask in the CC register is reset (RIM instruction).
