Once in the Idle mode the CPU status is preserved in its entirety: As inputs, Port 1 pins that are externally being pulled low will source current IIL, on the data sheet because of the internal pullups.
For other speed and temperature range availability please consult your sales office. D bytes of RAM.

Diagrams are for reference only. Receives the external oscillator signal when an external oscillator is used.
Port 0 is also the multiplexed low-order address and data bus during accesses to external Program and Data Memory. A high level on this for two machine cycles while the oscillator is running resets the device.
Program Store Enable output is the read strobe to external Program Memory. Port 0 also outputs the code bytes during program verification in the 80C D 64 K data memory space. Double Baud rate bit. Its hardware address is 87H. D 64 K program memory space. Search field Part name Part description. This pin should be floated when an external oscillator is used. Setting this bit activates idle mode operation. Port 0 pins that have 1’s written to them float, and in that state can be used as high-impedance inputs.
Idle and Power Down Hardware. As illustrated, Power Down operation stops the oscillator. In this application, it uses strong internal pullups when emitting 1’s. Package sizes are not to scale. In the power down mode the RAM is saved and all other functions are inoperative.
In this application it uses strong internal pullups when emitting 1’s. Port 1 pins that have 1’s written to them are pulled high by the internal pullups, and in that state can be used as inputs. As inputs, Port 3 pins that are externally being pulled low will source current ILL, on the data sheet because of the pullups. It also receives the high-order address bits and control signals during program verification in the 80C Input to the inverting amplifier that forms the oscillator.
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. D Programmable serial port.
D Fully static design. Idle mode operation allows the interrupt, serial port, and timer blocks to continue to function, while the clock to the CPU is gated off. Port 2 emits the high-order address byte during fetches from external Program Memory and during accesses to external Data.
D 6 interrupt sources. When set to a 1, the baud rate is doubled when the serial port is being used in either modes 1, 2 or 3. Port 1 also receives the low-order address byte during program verification.
In addition, the 80C52 has 2 software-selectable. Supply voltage during normal, Idle, and Power Down operation. The 80C52 retains all the features of the An internal pull-down resistor permits Power-On reset using only a capacitor connected to V.

Output of the inverting amplifier that forms the oscillator. This operation is achieved asynchronously even if the oscillator does not start-up. Idle And Power Down Operation. PCON is not bit addressable.
It can drive CMOS inputs without an external pullup. External pullups are required during program verification. As soon as the Reset is. In the idle mode the CPU is frozen while the RAM, the timers, the serial port and the interrupt system continue to function.
