We can Copying Microchip PIC16F59 Program, please view the Microchip PIC16F59 Program features for your reference:
The operation of the Synchronous Master and Slave modes are identical (see Section 12.4.1.3 “Synchronous Master Transmission”), except in the case of the Sleep mode.
If two words are written to the TXREG and then the SLEEP instruction is executed, the following will occur when copying microchip program:
- The first character will immediately transfer to the TSR register and transmit. The second word will remain in TXREG register. The TXIF bit will not be set.
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 if copying microchip program.
5. 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 routine by Crack MCU.
The operation of the Synchronous Master and Slave modes is identical (Section 12.4.1.5 “Synchronous Master Reception”), with the following exceptions:
- Sleep
- CREN bit is always set, therefore the receiver is never Idle
- SREN bit, which is a “don’t care” in Slave mode after copying microchip program
A character may be received while in Sleep mode by setting the CREN bit prior to entering Sleep. Once the word is received, the RSR register will transfer the data to the RCREG register when copying microchip program.
If the RCIE enable bit is set, the interrupt generated will wake the device from Sleep and execute the next instruction. If the GIE bit is also set, the program will branch to the interrupt vector if copying microchip program.
Set the SYNC and SPEN bits and clear the CSRC bit.
If using interrupts, ensure that the GIE and PEIE bits of the INTCON register are set and set the RCIE bit.
If 9-bit reception is desired, set the RX9 bit. Set the CREN bit to enable reception. The RCIF bit will be set when reception is complete. An interrupt will be generated if the RCIE bit was set before copying microchip program.
If 9-bit mode is enabled, retrieve the Most Significant bit from the RX9D bit of the RCSTA register. Retrieve the 8 Least Significant bits from the receive FIFO by reading the RCREG register.
If an overrun error occurs, clear the error by either clearing the CREN bit of the RCSTA register or by clearing the SPEN bit which resets the EUSART.
