We can Extract Code from Encrypted MCU PIC10F200, please view the MCU PIC10F200 features for your reference:
The SS pin allows a Synchronous Slave mode. The SPI must be in Slave mode with SS pin control enabled (SSPCON1<3:0> = 04h). The pin must not be driven low for the SS pin to function as an input. The data latch must be high. When the SS pin is low, transmission and reception are enabled and the SDO pin is driven.
When the SS pin goes high, the SDO pin is no longer driven, even if in the middle of a transmitted byte and becomes a floating output. External pull-up/pull-down resistors may be desirable depending on the application.When the SPI module resets, the bit counter is forced to ‘0’. This can be done by either forcing the SS pin to a high level or clearing the SSPEN bit when EXTRACT FIRMWARE OF MCU.
To emulate two-wire communication, the SDO pin can be connected to the SDI pin. When the SPI needs to operate as a receiver, the SDO pin can be configured as an input. This disables transmissions from the SDO. The SDI can always be left as an input (SDI function) since it cannot create a bus conflict.In SPI Master mode, module clocks may be operating at a different speed than when in full power mode; in the case of the Sleep mode, all clocks are halted IF THE CONTENT FROM FLASH CAN BE EXTRACTED.
In most Idle modes, a clock is provided to the peripherals. That clock should be from the primary clock source, the secondary clock (Timer1 oscillator at 32.768 kHz) or the INTOSC source. See Section 2.7 “Clock Sources and Oscillator Switching” for additional information. In most cases, the speed that the master clocks SPI data is not important; however, this should be evaluated for each system.
If MSSP interrupts are enabled, they can wake the controller from Sleep mode, or one of the Idle modes, when the master completes sending data. If an exit from Sleep or Idle mode is not desired, MSSP interrupts should be disabled; If the Sleep mode is selected, all module clocks are halted and the transmission/reception will remain in that state until the devices wakes to faciliate the process of MCU Cracking. After the device returns to Run mode, the module will resume transmitting and receiving data.
