Status Register (SR)
UART. Stop-Bit (length control). Selects the stop bit length Appended to the transmitted character. Stop-bit
lengths of 9/16th to 2 bits are programmable for 6- and 8-bit characters. Lengths of 1 1/16th to 2 bits are
programmable for 5-bit characters. In all cases, the receiver checks only for a high condition at the center of
the first stop-bit position, that is, one bit-time after the last data bit or after the parity bit, if parity is enabled.
Therefore, the receiver does not support a stop bit length less than 1. Not used in codec mode, see
Other Modes. Reserved.
Codec. Define the additional number of used RX and TX channels. Up to 3 RX channels are supported, but
the PSC interface only supports three data channels (TX + RX). Therefore, the maximum number of RX
channels is also depend on the programmed number of TX channels.
0000 One RX channel, one TX channel.
0001 One RX channel, two TX channels.
0010 Zero RX channel, three TX channels.
0100 Two RX channels, one TX channel.
1000 Three RX channels, zero TX channel.
