The receive FIFO buffer can hold two characters by Extract Microchip PIC16F1783 Microcontroller Code. An overrun error will be generated if a third character, in its entirety, is received before the FIFO is accessed. When this happens the OERR bit of the RCSTA register is set.
The characters already in the FIFO buffer can be read but no additional characters will be received until the error is cleared only after Extract MCU Binary File. The error must be cleared by either clearing the CREN bit of the RCSTA register or by resetting the EUSART by clearing the SPEN bit of the RCSTA register.
The EUSART supports 9-bit character reception. When the RX9 bit of the RCSTA register is set the EUSART will shift 9 bits into the RSR for each character received in the process of Extract Microcontroller AT89C1051 Code. The RX9D bit of the RCSTA register is the ninth and Most Significant data bit of the top unread character in the receive FIFO.
When reading 9-bit data from the receive FIFO buffer, the RX9D data bit must be read before reading the 8 Least Significant bits from the RCREG.
A special Address Detection mode is available for use when multiple receivers share the same transmission line on the process of Extract Microchip PIC16F1783 Microcontroller Code, such as in RS-485 systems. Address detection is enabled by setting the ADDEN bit of the RCSTA register.
Address detection requires 9-bit character reception. When address detection is enabled the progress of Extract IC Software, only characters with the ninth data bit set will be transferred to the receive FIFO buffer, thereby setting the RCIF interrupt bit. All other characters will be ignored.
Upon receiving an address character, user software determines if the address matches its own in order to Extract MCU AT89LV55 Code. Upon address match, user software must disable address detection by clearing the ADDEN bit before the next Stop bit occurs.
When user software detects the end of the message, determined by the message protocol used when IC Cloning, software places the receiver back into the Address Detection mode by setting the ADDEN bit.
