Note

When SCK is set to 1 and the baud rate generator output is selected, the ASCK pin can be used as

an input/output port.

This register is set when serial interface channel 2 is used in the asynchronous serial interface mode.

ASIM is set with a 1-bit or 8-bit memory manipulation instruction.

RESET input sets ASIM to 00H.
