CTRLC - USART Control Register C
• Bit 3 - TXEN: Transmitter Enable
Setting this bit enables the USART Transmitter. The Transmitter will override normal port opera-
tion for the TxD pin when enabled. Disabling the Transmitter (writing TXEN to zero) will not
become effective until ongoing and pending transmissions are completed, i.e., when the Trans-
mit Shift Register and Transmit Buffer Register do not contain data to be transmitted. When
disabled, the Transmitter will no longer override the TxD port.
• Bit 2 - CLK2X: Double Transmission Speed
Setting this bit will reduce the divisor of the baud rate divider from16 to 8 effectively doubling the
transfer rate for asynchronous communication modes. For synchronous operation this bit has no
effect and should always be written to zero. This bit must be zero when the USART Communica-
tion Mode is configured to IRCOM.
This bit is unused in Master SPI mode of operation.
• Bit 1 - MPCM: Multi-processor Communication Mode
This bit enables the Multi-processor Communication mode. When the MPCM bit is written to
one, the USART Receiver ignores all the incoming frames that do not contain address informa-
tion. The Transmitter is unaffected by the MPCM setting. For more detailed information see
”Multi-processor Communication Mode” on page
This bit is unused in Master SPI mode of operation.
• Bit 0 - TXB8: Transmit Bit 8
TXB8 is the ninth data bit in the character to be transmitted when operating with serial frames
with nine data bits. When used this bit must be written before writing the low bits to DATA.
This bit is unused in Master SPI mode of operation.
Note:
• Bits 7:6 - CMODE[1:0]: USART Communication Mode
These bits select the mode of operation of the USART as shown in
Table 21-6.
