Interrupt Priority Control High 1. Alternate function of Port 4.

Timer 0, Timer 1 and Timer 2 Signal Description. To avoid any parasitic current. This pin has an internal pull-up resistor which allows the device to be reset. Power and clock control registers: Port 0Port 1 Port 2 Port 3 Port 4. SCL output the serial clock to slave peripherals.

In the idle mode the CPU is frozen while the timers, the serial. Input to the on-chip inverting oscillator amplifier.

These pins can be directly connected to the Cathode of standard LEDs. The serial input is P3. Alternate function of Port datashret. P0, P1, P2, P3, P4. The falling edge of ALE strobes the address into external latch. Data LSB for Slave port access used for 8-bit and bit modes.

USB pull-up Controlled Output. IE0 are set by a falling edge on INT0. Interrupt Priority Control High 0. AT89C has two software-selectable modes of reduced activity for further reduction. In the power-down mode the RAM is. The X1 pin can also be used as input for an external 48 MHz clock. VDD is used to supply the buffer ring on all versions of the device. The AT89C clock controller is based on an on-chip oscillator feeding an on-chip. Interrupt Priority Control Low 0.

Control input for slave port read access cycles. Low Power Voltage Range. Timer 1 Gate Input. USB Data – signal. Write signal asserted during external data memory write operation. Hardware Watchdog Timer at89cc5131 In standard versions, the Vref output voltage is equal to the internal.
