CFGQ Silicon Laboratories Inc, CFGQ Datasheet
Crystal Oscillator is unused or not darasheet stable. Program and data memory share the same address space but are accessed via different instruction types. Instructions are read from Flash memory two bytes at a time by the prefetch engine, and given to the CIP processor core to execute Calibrating the ADC ADC0 can be calibrated in-system for both gain and offset, using internal or system calibration modes.
ADC operates in Unipolar mode straight binary result. The winning master continues its transmission without interruption; the losing master becomes a slave and receives the rest of the transfer if addressed.
Not a good practise! Note that this pin assignment is inde- pendent of the Crossbar The three Flash access methods that can be restricted are reads, writes, and erases from c8051g350 C2 debug interface, user firmware executing on unlocked pages, and user firmware executing on locked pages. Enable interrupt requests generated by SMB0. Reset Sources Figure Analog Input Configuration Bits for P1.
Timer 0 and Timer Clock Low Extension SMBus provides a clock synchronization mechanism, similar to I2C, which allows devices with different speed capabilities to coexist on the bus.
Comparator0 Inputs and Outputs This bit sets the priority of the Timer 3 interrupt.

Even though DACs working frequency is in Mhz. A Slave byte was transmitted error detected. Each of the serial buses is fully implemented in hard- ware and makes extensive use of the CIP’s interrupts, thus requiring very little CPU intervention.
There are two sep- arate memory spaces: Important note f8051f350 the SI bit: This arbitration scheme is non-destructive: Port c80511f350 drivers are disabled while the Crossbar is disabled. V monitor is a reset source. Refer to Table This bit sets the priority of the SPI0 interrupt.
Revision Specific Behavior Figure C2D P0 P0 P0. The memory map is shown in Figure SMBus operating in Master Mode.
These bits select which Port pin is used as the Comparator0 negative input. C2 Revision C2 Register Definition External crystals and ceramic resonators typ- ically require a start-up time before they are settled and ready for use. The first key code has been written 0xA5. The temperature sensor is automatically enabled when it is selected with the ADC multi- plexer.
Supporting Documents It is assumed the reader is familiar with or has access to the following supporting documents: This register contains bits 7—0 of the bit ADC fast filter conversion result.
Elcodis is a trademark of Elcodis Company Ltd. This bit sets the masking of the SMB0 interrupt. It must then deactivate the interrupt request before execution of the ISR completes or another interrupt request will be generated.

The user can program both the amount of hysteresis voltage referred to the input voltage and the positive and negative-going symmetry of this hysteresis around the threshold voltage. Enable the external oscillator. The TH0 register is restricted to a timer function sourced by the system clock or prescaled clock All other trademarks are the property of their respective owners. When the ADC is disabled placed in a low-power shutdown mode with all clocks turned off, to minimize unnecessary power consumption.
Comparator0 Asynchronous Output Enable 0: In this case, the response time is 18 system clock cycles: This bit is set when the last arithmetic operation resulted in a carry addition borrow subtraction cleared all other arithmetic operations. Well the problem has been solved, it was somewhere timing error as mentioned above by Some Hardware Guy. Analog Input Configuration Bits for P0. Proce- dures for single and continuous conversion modes are detailed in the sections below By requiring less intervention from the microcontroller core, an interrupt-driven system is more efficient and allows for easier implemen- tation of multi-tasking, real-time systems Set STA to restart transfer.
