Set automatically at power-on to indicate that the PLL loop is correctly tracking the crystal datassheet. PSEN enables serial download mode when pulled low through a resistor on power-up or reset.

Clock Polarity Select Bit. Priority for power supply monitor interrupt. In this application, it uses strong internal pull-ups when datwsheet 1s.

Set by the user to enable, or cleared to disable time interval counter interrupts. The various ranges specified are as follows: Set by the user to 1 to select an external clock input on P3. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. In addition to the basic UART connections, users also need a way to trigger the chip into download mode.

The SFR registers include control, configuration, and data registers, which provide an interface between the CPU and all on-chip peripherals. However, reading the memory in parallel mode and reading the memory via a MOVC command from external memory is still allowed.

Baud rate generation is described as part of the UART serial port operation in the following section. If you do, however, be sure to include the Schottky diodes shown in Figure 31 or at least datashewt lower of the two diodes to protect the analog input from undervoltage conditions.


This interface is standard to any compatible MCU. A read-only status bit that is set during a valid ADC conversion or during a calibration cycle.

Port 3 Alternate Pin Functions P3.

Due to this, instructions that access the TIC registers are also clocked at this speed. Figure 22 shows the voltage output of the on-chip temperature sensor datasueet temperature. To be more specific, a byte can datashheet programmed only if it already holds the value FFH. Main Data Pointer Mode.

Acquisition and conversion times are also fully configurable under user control. Initial page erase sequence. However, there is also the option datashee allow SPI operate separately on P3. Port 2 also emits the highorder address bytes during fetches from external program memory, and middle and high order address bytes during accesses to the bit external data memory space. The following code can be used to monitor the BUSY signal during a calibration cycle: Set by software to specify edge-sensitive detection, that is, 1-to-0 transition.

SPI is an industrystandard synchronous serial datashet that allows 8 bits of data to be synchronously transmitted and received simultaneously, that is, full duplex. Twin 8-bit PWM 0 1 1 Mode 3: PWM Disabled 0 0 1 Mode 1: Package Description The package for this IC i.

Voltage Output from DAC0. To summarize this section, use the circuit in Figure 31 to drive the analog input pins of the parts. Adcu841 78 shows a hardware configuration for accessing up to 64 kBytes of external RAM.


At least one model within this product family is in production and available for purchase. Read 1 indicates that the DVDD supply is above its selected trip point. TxD This is the case if, and only if, all of the following conditions are met at aduc81 time the final shift pulse is generated: The reload leaves TH0 unchanged.

The specific part is obsolete and no longer available. During the conversion phase with both switches in the hold positionthe dztasheet DAC is adjusted via internal SAR logic until the voltage on Node A is 0, dagasheet that the sampled charge on the input capacitor is balanced out by the charge being output by the capacitor DAC.

But somewhere around 7 mA, the upper curve in Figure 45 drops below 2. Two bit voltage output DACs 1.

Pricing displayed is based on 1-piece. For that reason, do not use a reference voltage lower than 1 V.

External Memory Address A2. This mode is deactivated by initiating a code-erase command in serial download or parallel programming modes.

The model has not been released to general production, but samples may be available. Note that the repeated start is detected only when a slave has previously been configured as a receiver. Since aduc814 takes two machine cycles two core clock periods to recognize a 1-to-0 transition, the maximum count rate is half the core clock frequency.
