Microchip PIC18F26J50 Microcontroller Flash Content Extraction for some reason will be required to enter the synchronous slave mode which will provide more benefit for the whole process:
The following bits are used to configure the EUSART for Synchronous slave operation when proceed with MCU Reading:
- SYNC = 1
- CSRC = 0
- SREN = 0 (for transmit); SREN = 1 (for receive)
- CREN = 0 (for transmit); CREN = 1 (for receive)
- SPEN = 1
Setting the SYNC bit of the TXSTA register configures the device for synchronous operation. Clearing the CSRC bit of the TXSTA register configures the device as a slave by MCU Extraction. Clearing the SREN and CREN bits of the RCSTA register ensures that the device is in the Transmit mode, otherwise the device will be configured to receive. Setting the SPEN bit of the RCSTA register enables the EUSART.
The operation of the Synchronous Master and Slave modes are identical (see Section 22.5.1.3 “Synchronous Master Transmission”), except in the case of the Sleep mode after Extract IC AT89C51ED2 Code.
If two words are written to the TXREG and then the SLEEP instruction is executed, the following will occur:
- The first character will immediately transfer to the TSR register and
- The second word will remain in TXREG
- The TXIF bit will not be
- After the first character has been shifted out of TSR, the TXREG register will transfer the second character to the TSR and the TXIF bit will now be set before Extract MCU AT89C51RD2 Eeprom.
- If the PEIE and TXIE bits are set, the interrupt will wake the device from Sleep and execute the next instruction. If the GIE bit is also set, the program will call the Interrupt Service
Synchronous Slave Transmission Set-up:
- Set the SYNC and SPEN bits and clear the CSRC
- Clear the ANSEL bit for the CK pin (if applicable).
- Clear the CREN and SREN
- If interrupts are desired, set the TXIE bit of the PIE1 register and the GIE and PEIE bits of the INTCON
- If 9-bit transmission is desired, set the TX9
- Enable transmission by setting the TXEN
- If 9-bit transmission is selected, insert the Most Significant bit into the TX9D by Break IC Flash
- Start transmission by writing the Least Significant 8 bits to the TXREG.
