没用过78K0R,官方也没找到这个芯片的PDF,找到个类似的78K0R/IC3的PDF,下面的文字或许对你有帮助。
Cautions 1. To use P70/SO01/INTP4, P71/SI01/INTP5, P72/SCK01/INTP6, P73/SO00/TxD0/TO10, P74/SI00/
RxD0/TI10, P75/SCK00/TI11 (38-pin products of 78K0R/IC3: P72/INTP6/RxD0, P73/TxD0/TO10)
as a general-purpose port, note the serial array unit setting. For details, refer to the following
tables.
In case of the 44-pin and 48-pin products of 78K0R/IC3, 78K0R/ID3, and 78K0R/IE3
• Table 13-7 Relationship Between Register Settings and Pins (Channel 0: CSI00, UART0
Transmission)
• Table 13-10 Relationship Between Register Settings and Pins (Channel 1: CSI01, UART0
Reception).
In case of the 78K0R/IB3
• Table 13-6 Relationship Between Register Settings and Pins (Channel 0: UART0
Transmission)
• Table 13-9 Relationship Between Register Settings and Pins (Channel 1: UART0
