Serial Programming RAJ240080 chip series ?


Does it support 1-Wire serial programming (TOOL0) or only dual-wire ? In this last case, which Tx/Rx pin is used (TxD0/RxD0 or TxD1/RxD1) ? What programming protocol does this chip support (from A to D) ?

The datasheet only talks about "TOOLRxD/TOOLTxD" mode (00H=Dual Wire mode) but theses pins are not defined.

Many thanks.

Best regards
