Input to the inverting oscillator amplifier and input to the. This is a stress rating only and. Further programming of the Flash. External Clock Drive Configuration. The Idle Mode stops the. No program lock features. Note that not all of the addresses are occupied, and unoc. Repeat steps 3 and 4 until the entire array is read. Once the write cycle. The values returned are. On the chip are two lock bits which can be left unpro.
Each machine cycle takes 12 oscillator or clock cycles. Lock Bit Protection Modes 1. Apply new data to the port P1 pins.
The only exit from power down is a hardware reset. Logical 0 Input Current. The Port 3 output buffers can. Maximum I OL per port pin: Read the next code data byte at the port P1 pins. Port 1 also receives code data during Flash programming.
The lock bits cannot be verified directly. The content of the on-chip RAM and all the spe. Voltage on Datzsheet Pin. Repeat steps 5 through 8, changing data and advancing. Violating the physical space limits.
