Notes
1. If the external clock input has been selected with CSIM11 set to 0, set bit 1 (BUSY1) and bit 2 (STRB)
of the automatic data transmit/receive control register (ADTC) to 0 and 0, respectively.
2. Can be used freely as port function.
3. Can be used as P20 (CMOS input/output) when only transmitter is used (Set bit 7 (RE) of ADTC to 0).

(b) Automatic data transmit/receive control register (ADTC)
ADTC is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets ADTC to 00H.
