Read Protected MCU PIC18F8622 Heximal out from microcontroller’s locked memory which include flash and eeprom, then copy the firmware into new MCU PIC18F8622 for the IC duplication;
In Capture mode, the CCPRxH:CCPRxL register pair captures the 16-bit value of the TMR1 or TMR3 registers when an event occurs on the corresponding CCPx pin. An event is defined as one of the following:
• every falling edge The event is selected by the mode select bits, CCPxM3:CCPxM0 (CCPxCON<3:0>).
When a capture is made, the interrupt request flag bit, CCPxIF, is set; it must be cleared in software. If another capture occurs before the value in register CCPRx is read, the old captured value is overwritten by the new captured value. In Capture mode, the appropriate CCPx pin should be configured as an input by setting the corresponding TRIS direction bit when read protected mcu pic18f2480 code.
The timers that are to be used with the capture feature (Timer1 and/or Timer3) must be running in Timer mode or Synchronized Counter mode. In Asynchronous Counter mode, the capture operation will not work. The timer to be used with each CCP module is selected in the T3CON register (see Section 15.1.1 “CCP Modules and Timer Resources”) if the protected microcontroller pic18f2510 can be copied.
When the Capture mode is changed, a false capture interrupt may be generated. The user should keep the CCPxIE interrupt enable bit clear to avoid false interrupts. The interrupt flag bit, CCPxIF, should also be cleared following any such change in operating mode. There are four prescaler settings in Capture mode; they are specified as part of the operating mode selected bythe mode select bits (CCPxM3:CCPxM0).
Whenever the CCP module is turned off or Capture mode is disabled, the prescaler counter is cleared. This means that any Reset will clear the prescaler counter.
Switching from one capture prescaler to another may generate an interrupt. Also, the prescaler counter will not be cleared; therefore, the first capture may be from a non-zero prescaler. Example 15-1 shows the recommended method for switching between capture prescalers when Crack MCU. This example also clears the prescaler counter and will not generate the “false” interrupt.
