Default Description PowerWell ResetSignal
2 RW 1'h0 Number of stop bits (STOP)
Used to select the number of
stop bits per character that
the peripheral will transmit
and receive. If set to zero, one
stop bit is transmitted in the
serial data. If set to one and
the data bits are set to 5
(LCR[1:0] set to zero) one and
a half stop bits is transmitted.
Otherwise, two stop bits are
transmitted. NOTE that
regardless of the number of
stop bits selected the receiver
will only check the first stop
bit.
0 = 1 stop bit
1 = 1.5 stop bits when DLS
(LCR[1:0]) == 00
1 = 2 stop bits when DLS
(LCR[1:0]) different from 00
1:0 RW 2'h0 Data Length Select (DLS)
Data Length Select. If
UART_16550_COMPATIBLE =
NO, then writeable only when
UART is not busy (USR[0] is
0); otherwise always writable,
always readable. When DLS_E
in LCR_EXT is set to 0, this is
used to select the number of
data bits per character that
the peripheral transmits and
receives. The number of bit
that may be selected are as
follows:
00 5 bits
01 6 bits
10 7 bits
11 8 bits
