Setting this bit activates idle mode operation. Package sizes are not to scale.
Diagrams are for reference only. Table 1 describes the status of the external pins during Idle mode. It can drive CMOS inputs without an external pullup. Port 2 emits the high-order address byte during fetches from external 80c25 Memory and during accesses to external Data. As inputs, Port 1 pins that are externally being pulled low will source current IIL, on the data sheet because of the internal pullups.

Idle and Power Down Hardware. In this application it uses strong internal pullups when emitting 1’s. Romless version of the 80C Receives the external oscillator signal when an external oscillator is used. Double Baud rate bit. Port 0 also outputs the code bytes during program verification in the 80C In this application, it uses strong internal pullups when emitting 1’s.
D 6 interrupt sources. PCON is not bit addressable. An internal pull-down resistor permits Power-On reset using only a capacitor connected to V.

For other speed vatasheet temperature range availability please consult your sales office. 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.
Idle mode operation allows the interrupt, serial port, and timer blocks to continue to function, while the clock to the CPU is gated off.
When set to a 1, the baud rate is doubled when the serial port is being used in either modes 1, 2 or 3. In the power down mode the RAM is saved and all other functions are inoperative. Input to the inverting amplifier that forms the oscillator.

D Fully static design. D 64 K program memory space. As inputs, Port 3 pins that are externally being pulled low will source current ILL, on the data sheet because of the pullups.
Its hardware address is 87H. As illustrated, Power Down operation stops the oscillator. Port 1 also receives the low-order address byte during program verification. Search field Part name Part description. This pin should be floated when an external oscillator is used. D Power control modes. The 80C52 retains all the features of the Address Latch Enable output for latching the low byte of the datasheey during accesses to external memory.
Output of the inverting amplifier that forms the oscillator. Program Store Enable output is the read strobe to external Program Memory. The instruction that sets PCON.
