• Bit 7:5 –Reserved Bits

These bits are reserved for future use. For compatibilty with future devices, these bits must be

written to zero when EUSCRB is written.

• Bit 4 – EUSART Enable Bit

Set to enable the EUSART mode, clear to operate as standard USART.

• Bit 3– EUSBS Enable Bit

This bit selects the number of stop bits detected by the receiver.

Note: The number of stop bit inserted by the Transmitter in EUSART mode is configurable through the

USBS bit of in the of the USART.

• Bit 2–Reserved Bit

This bit is reserved for future use. For compatibility with future devices, this bit must be written to

zero when EUSCRB is written.

• Bit 1 – Manchester mode

When set the EUSART operates in manchester encoder/decoder mode (Manchester encoded

frames). When cleared the EUSART detected and transmit level encoded frames.
