ASIM00
Cautions 1. Bits 0 and 1 must be fixed to 0.
Symbol
Asynchronous serial interface mode register 00 (ASIM00)
This register is set when using serial interface 00 in the asynchronous serial interface mode.
ASIM00 is set using a 1-bit or 8-bit memory manipulation instruction.
RESET input sets ASIM00 to 00H.
