The instruction that sets PCON. Port 0 also outputs the code bytes during program verification in the 80C It can drive CMOS inputs without an external pullup.
Port 1 pins that have 1’s written to them are pulled dayasheet by the internal pullups, and in that state can be used as inputs.

D 64 K data memory space. As inputs, Port 1 pins that are externally being pulled low will source current IIL, on the datashedt sheet because of the internal pullups. Figure 3 shows the internal Idle and Power Down clock configuration. Address Latch Enable output for latching the low byte of the address during accesses to external memory. This pin should be floated when an external oscillator is used. In the idle mode the CPU is frozen while the RAM, the timers, the serial port and the interrupt system continue to function.
As inputs, Port 2 pins that are datashert being pulled low will source current ILL, on the data sheet because of the internal pullups. When set to a 1, the baud rate is doubled when datasneet serial port is being used in either modes 1, 2 or 3. External pullups are required during program verification. D Power control modes. Program Store Enable output is the read strobe to external Program Memory. The 80C52 retains all the features of the As inputs, Port 3 pins that are externally being pulled low will source current ILL, on the data sheet because of the pullups.
80C52 Technical Data
Idle And Power Down Operation. PCON is not bit addressable. Once in the Idle mode the CPU status is preserved in its entirety: It also receives the high-order address bits and control signals during program verification in the 80C Port 0 pins that have 1’s written to them float, and in that state can be used as high-impedance inputs.
Package sizes are not to scale. Diagrams are for reference only. D 6 interrupt sources.
Port 3 pins that have 1’s written to them are pulled high by the internal pullups, and in that state can be used as inputs. Receives the external oscillator signal when an external oscillator is used. D Programmable serial port.
Port 0 is also the multiplexed low-order address and data bus during accesses to external Program and Data Memory. In datzsheet application, it uses strong internal pullups when emitting 1’s.
A high level on this for two machine cycles while the oscillator is running resets the device. D bytes of RAM. Supply voltage during normal, Idle, and Power Down operation.
Port 2 emits the high-order address byte during fetches from external Program Memory and during accesses to external Data. EA must not be floated. It can drive CMOS inputs without external pullups. D Fully static design. An internal pull-down resistor permits Power-On reset using only a capacitor connected to V. Romless version of the 80C Input to the inverting amplifier that forms the oscillator.
