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) P3.2 program verification of the ROM and EPROM parts. P3,3 INT1 (external interrupt 1) P3.4 TO(Timer Oe.
