We can Unlock locked chip Microchip PIC18LF242 program, please view the Microchip PIC18LF242 features for your reference:
The Hi-Resolution (Hi-Res) Extension is able to increase the resolution of the waveform generation output by a factor of 4. When enabled for a Timer/Counter, the Fast Peripheral clock running at four times the CPU clock speed will be as input to the Timer/Counter when Unlock program from Unlock Locked Chip Microchip PIC18LF242 Program.
The High Resolution Extension can also be used when an AWEX is enabled and used with a Timer/Counter. XMEGA A1 devices have four Hi-Res Extensions that each can be enabled for each Timer/Counters pair on PORTC, PORTD, PORTE and PORTF. The notation of these peripherals are HIRESC, HIRESD, HIRESE and HIRESF, respectively.
The XMEGA A1 includes a 16-bit Real-time Counter (RTC). The RTC can be clocked from an accurate 32.768 kHz Crystal Oscillator, the 32.768 kHz Calibrated Internal Oscillator, or from the 32 kHz Ultra Low Power Internal Oscillator. The RTC includes both a Period and a Compare register if Unlock Locked Chip Microchip PIC18LF242 Program.
A wide range of Resolution and Time-out periods can be configured using the RTC. With a maximum resolution of 30.5 µs, time-out periods range up to 2000 seconds. With a resolution of 1 second, the maximum time-out period is over 18 hours (65536 seconds).

I2C and System Management Bus (SMBus) compatible before Unlock Locked Chip Microchip PIC18LF242 Program
The Two-Wire Interface (TWI) is a bi-directional wired-AND bus with only two lines, the clock (SCL) line and the data (SDA) line. The protocol makes it possible to interconnect up to 128 individually addressable devices. Since it is a multi-master bus, one or more devices capable of taking control of the bus can be connected.
The only external hardware needed to implement the bus is a single pull-up resistor for each of the TWI bus lines. Mechanisms for resolving bus contention are inherent in the TWI protocol. PORTC, PORTD, PORTE, and PORTF each has one TWI. Notation of these peripherals are TWIC, TWID, TWIE, and TWIF, respectively after CRACK MCU.
