Unlock Microchip PIC12F615 MCU Flash Memory
Unlock Microchip PIC12F615 MCU Flash Memory and extract embedded firmware from PIC12F615 microcontroller original IC MCU PIC12F615 chip protection can be broken off;
For PIC12F615 devices, the WDT is driven by the INTRC source. When the WDT is enabled, the clock source is also enabled. The nominal WDT period is 4 ms and has the same stability as the INTRC oscillator to break microchip pic12f1571 mcu protection.
The 4 ms period of the WDT is multiplied by a 16-bit postscaler. Any output of the WDT postscaler is selected by a multiplexer, controlled by bits in Configuration Register 2H. Available periods range from 4 ms to
131.072 seconds (2.18 minutes). The WDT and postscaler are cleared when any of the following events occur: execute a SLEEP or CLRWDT instruction by breaking microchip pic12f508 processor flash memory, the IRCF bits (OSCCON<6:4>) are changed or a clock failure has occurred.
Adjustments to the internal oscillator clock period using the OSCTUNE register also affect the period of the WDT by the same factor. For example, if the INTRC period is increased by 3%, then the WDT period is increased by 3%.
Register 19-14 shows the WDTCON register. This is a readable and writable register, which contains a control bit that allows software to override the WDT enable Configuration bit, only if the Configuration bit has disabled the WDT.
