Timer 3 can be used instead of Timer 1 or Timer 2 for generating very accurate high speed UART baud rates vatasheet and This bit should always contain 0.

These two bits enable extra modes of the main data pointer operation, allowing for more compact and more efficient code size and execution. Acquisition and conversion times are also fully configurable under user control. Serial Port Receive Interrupt Flag.

Port 2 emits the middle-order address byte during accesses to the external bit external data memory space. The ADC is using its internal reference 2. The CD bits should not be set to 0 on a 3 V part. BoxNorwood, MAU. Byte program sequence memory. Baud rate generation is described as part of the UART serial port operation in the following section. TL1 serves as 5-bit prescaler. Priority for power supply monitor interrupt. This allows a master to change direction of transfer without aduc81 up the bus.


This mode is deactivated by initiating a code-erase command in serial download or parallel programming modes. Control of the SAR and timing of acquisition and sampling modes is handled automatically by built-in ADC control logic.

Note that the 5 V part has an internal POR trip level of 4. If SM2 is cleared, RI is set as soon as the byte of data has been received. Timer 2 External Flag. The physical interface to the serial data network is via Pins RxD P3.

If the watchdog datasheeg not being used to monitor the system, it can be used alternatively as a timer. Make sure the return paths for all currents are as close as possible to the paths that the currents took to Rev.

Port 2 pins with 0s written to them drive a logic low output voltage VOL and are capable of sinking 1.

Model Package Pins Temp. The appropriate value for T3FD can be calculated with the following formula: But at clock speeds slower that kHz, the ADC can no longer function correctly. The supply monitor is also protected against spurious glitches triggering the interrupt circuit.

These functions are described in Application Note uC Both PWMs have the same clock source datashwet clock divider.

Read 1 indicates that the DVDD supply is above its selected trip point. This is not available in the QuickStart System, but there dztasheet an example project that demonstrates this capability. But somewhere around 7 mA, the upper curve in Figure 45 drops below 2. A Page 94 of 95 0. In 0 V-to-VREF mode, DAC loading does not cause high-side voltage drops as long as the reference voltage remains below the upper trace in the corresponding figure. Set to 0 by the user to enable the DAC output buffer.



Features full C datxsheet assembly emulation using the Accutron single pin emulator. Interval Timebase Selection Bits. Therefore, the user can enable only one interface or the other on these pins at any given time see SPE in Table Lock Mode This mode locks the code memory, disabling parallel programming of the program memory. To address this problem, the part has added a dedicated baud rate timer Timer 3 specifically for generating highly accurate baud rates.

If you do, however, be sure to include the Schottky diodes shown in Figure 31 or at least the lower of the two diodes to protect the analog input from undervoltage conditions. Set by hardware to indicate the source of an I2C interrupt. DGND is the ground reference point for the digital circuitry.
