Copy Secured MCU PIC18F8621 Heximal from its flash and eeprom memory, then replicate the firmware to new Microontroller PIC18F8621 for the perfect cloning which is the completion of MCU cracking process;
PIC18F8621 devices all have two CCP (Capture/Compare/PWM) modules. Each module contains a 16-bit register which can operate as a 16-bit Capture register, a 16-bit Compare register or a PWM Master/Slave Duty Cycle register.
In 28-pin devices, the two standard CCP modules (CCP1 and CCP2) operate as described in this chapter. In 40/
44-pin devices, CCP1 is implemented as an enhanced CCP module with standard Capture and Compare modes and enhanced PWM modes. The ECCP implementation is discussed in Section 16.0 “Enhanced Capture/Compare/PWM (ECCP) Module” when extract microcontroller PIC18F2439 memory program.
The Capture and Compare operations described in this chapter apply to all standard and enhanced CCP modules. Note: Throughout this section and Section 16.0 “Enhanced Capture/Compare/PWM (ECCP) Module”, references to the register and bit names for CCP modules are referred to generically by the use of ‘x’ or ‘y’ in place of the specific module number. Thus, “CCPxCON” might refer to the control register for CCP1, CCP2 or ECCP1. “CCPxCON” is used throughout these sections to refer to the module control register, regardless of whether the CCP module is a standard or enhanced implementation.
Each Capture/Compare/PWM module is associated with a control register (generically, CCPxCON) and a data register (CCPRx). The data register, in turn, is comprised of two 8-bit registers: CCPRxL (low byte) and CCPRxH (high byte). All registers are both readable and writable. The CCP modules utilize Timers 1, 2 or 3, depending on the mode selected. Timer1 and Timer3 are available to modules in Capture or Compare modes, while Timer2 is available for modules in PWM mode. The assignment of a particular timer to a module is determined by the Timer-to-CCP enable bits in the T3CON register (Register 14-1). Both modules may be active at any given time and may share the same timer resource if they are configured to operate in the same mode (Capture/Compare or PWM) at the same time before copy heximal from mcu pic18f2455.
The interactions between the two modules are summarized in Figure 15-1 and Figure 15-2. In Timer1 in Asynchronous Counter mode, the capture operation will not work. The pin assignment for CCP2 (Capture input, Compare and PWM output) can change, based on device configuration. The CCP2MX configuration bit determines which pin CCP2 is multiplexed to in order to crack MCU. By default, it is assigned to RC1 (CCP2MX = 1). If the configuration bit is cleared, CCP2 is multiplexed with RB3. Changing the pin assignment of CCP2 does not automatically change any requirements for configuring the port pin. Users must always verify that the appropriate TRIS register is configured correctly for CCP2 operation, regardless of where it is located.
