Features
- of the MCS 51 Family, as listed below: written to them are pulled high by the internal pullDataSheet4U. com UPS,and in that state can be used as inputs. As inputs, Port 1 pins that are externally pulled low will Port Alternative Function source current (IIL on the data sheet) because of the Pin internal pullups. RXD (serial input port) P3,0 Port 1 also receives the low-order address bytes P3.1 TXD (serial output port) during programming of the EPROM parts and during INTO(external interrupt O) P3.
