Receiver
The receiver is enabled through its UCRn, as described in Section 23.3.5, 鈥淯ART Command Registers
When the receiver detects a high-to-low (mark-to-space) transition of the start bit on URXDn, the state of
URXDn is sampled eight times on the edge of the bit time clock starting one-half clock after the transition
(asynchronous operation) or at the next rising edge of the bit time clock (synchronous operation). If
URXDn is sampled high, start bit is invalid and the search for the valid start bit begins again.
If URXDn remains low, a valid start bit is assumed. The receiver continues sampling the input at one-bit
time intervals at the theoretical center of the bit until the proper number of data bits and parity, if any, is
assembled and one stop bit is detected. Data on the URXDn input is sampled on the rising edge of the
programmed clock source. The lsb is received first. The data then transfers to a receiver holding register
and USRn[RXRDY] is set. If the character is less than 8 bits, the most significant unused bits in the
receiver holding register are cleared.
After the stop bit is detected, receiver immediately looks for the next start bit. However, if a non-zero
character is received without a stop bit (framing error) and URXDn remains low for one-half of the bit
period after the stop bit is sampled, receiver operates as if a new start bit were detected. Parity error,
