UAnFE
• Only the first bit of the receive data is checked as a stop bit, regardless of the value of the UAnSL bit of the
UAnCTL0 register.
• Although the UAnFE bit can be read or written, it can only be cleared by writing 0, and cannot be set by writ-
ing 1. It holds the current status when 1 is written.
UAnOVE
• If an overrun error occurs, the next receive data is not written to the receive buffer but discarded.
• Although the UAnOVE bit can be read or written, it can only be cleared by writing 0, and cannot be set by
writing 1. It holds the current status when 1 is written.
