CTRLA – USART Control Register A
CTRLB - USART Control Register B
This bit is unused in Master SPI mode of operation.
• Bit 7:6 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 5:4 - RXCINTLVL[1:0]: Receive Complete Interrupt Level
These bits enable the Receive Complete Interrupt and select the interrupt level as described in
”Interrupts and Programmable Multi-level Interrupt Controller” on page
will be triggered when the RXCIF in the STATUS register is set.
• Bit 3:2 - TXCINTLVL[1:0]: Transmit Complete Interrupt Level
These bits enable the Transmit Complete Interrupt and select the interrupt level as described in
”Interrupts and Programmable Multi-level Interrupt Controller” on page
will be triggered when the TXCIF in the STATUS register is set.
• Bit 1:0 - DREINTLVL[1:0]: USART Data Register Empty Interrupt Level
These bits enable the Data Register Empty Interrupt and select the interrupt level as described
in
rupt will be triggered when the DREIF in the STATUS register is set.
• Bit 7:5 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 4 - RXEN: Receiver Enable
Writing this bit to one enables the USART Receiver. The Receiver will override normal port oper-
ation for the RxD pin when enabled. Disabling the Receiver will flush the receive buffer
invalidating the FERR, BUFOVF, and PERR flags.
• Bit 3 - TXEN: Transmitter Enable
Writing this bit to one enables the USART Transmitter. The Transmitter will override normal port
operation for the TxD pin when enabled. Disabling the Transmitter (writing TXEN to zero) will not
