Revision A1
Bit 4: EPE. This bit describes the number of logic 1's in the data word bits and parity bit only when bit
3 is programmed. When this bit is set, an even number of logic 1's are sent or checked. When
the bit is reset, an odd number of logic 1's are sent or checked.
Bit 3: PBE. When this bit is set, the position between the last data bit and the stop bit of the SOUT
will be stuffed with the parity bit at the transmitter. For the receiver, the parity bit in the same
position as the transmitter will be detected.
Bit 2: MSBE. This bit defines the number of stop bits in each serial character that is transmitted or
received.
(1) If MSBE is set to a logical 0, one stop bit is sent and checked.
(2) If MSBE is set to a logical 1, and data length is 5 bits, one and a half stop bits are sent and
checked.
(3) If MSBE is set to a logical 1, and data length is 6, 7, or 8 bits, two stop bits are sent and
checked.
Bits 0 and 1: DLS0, DLS1. These two bits define the number of data bits that are sent or checked in
each serial character.
