If bit IT1 is cleared, bits IE1 is set by. AT89C is a high-performance Flash version of the 80C51 single-chip 8-bit micro. All the internal clocks to the peripherals and CPU core are gen. If bit IT0 is cleared, bits IE0 is set by. SCL input the serial clock from master. Interrupt Priority Control High 0. IE0 are set by a falling edge on INT0. In standard versions, the Vref output voltage is equal to the internal. VSS is at89f5131 to supply the buffer ring and eatasheet digital core.
Port 0Port 1 Port 2 Port 3 Port 4. Output of the on-chip inverting oscillator amplifier. Interrupt Enable Control 0.
Address Bus MSB for external access. If bit IT1 in this register is set, bits. Holding this pin low for 64 oscillator periods while the oscillator is running.
Timer 0 Gate Input. When Timer 0 operates as a counter, a falling edge on the T0 pin.
It is also used to power the on-chip voltage regulator of the Standard. Timer 1 Gate Input. Alternate function of Port 4. SCK outputs clock to the slave peripheral or receive clock from the master. These pins can be directly connected to the Cathode of standard LEDs. Interrupt Priority Control Low 0. Power and clock control registers: USB Data – signal. The table below shows all SFRs with their address and their reset value.
Input to the on-chip inverting oscillator amplifier. This pin must be set to V DD for normal operation. Endpoint 0 for Control Transfers: The typical current of each. A Max Power-down Current. Idle and Power-down Modes. Hardware Watchdog Timer registers: Keypad Interface Signal Description.
This pin has an internal pull-up resistor which allows the device to be reset. To avoid any parasitic current.
Data LSB for Slave port access used for 8-bit and bit modes. It is latched during reset and. P0, P1, P2, P3, P4.
