PT—Parity Type
B/C1–B/C0—Bits per Character
MOTOROLA
This bit controls the meaning of the three FIFO status bits (RB, FE, and PE) in the SR
for the channel.
These bits encode the type of parity used for the channel (see Table 7-2). The parity bit
is added to the transmitted character, and the receiver performs a parity check on
incoming data. These bits can alternatively select multidrop mode for the channel.
This bit selects the parity type if parity is programmed by the parity mode bits, and if
multidrop mode is selected, it configures the transmitter for data character transmission
or address character transmission. Table 7-2 lists the parity mode and type or the
multidrop mode for each combination of the parity mode and the parity type bits.
These bits select the number of data bits per character to be transmitted. The character
length listed in Table 7-3 does not include start, parity, or stop bits.
1 = Block mode—The values in the channel SR are the accumulation (i.e., the logical
0 = Character mode—The values in the channel SR reflect the status of the
OR) of the status for all characters coming to the top of the FIFO since the last
reset error status command for the channel was issued. Refer to 7.4.1.7
Command Register (CR) for more information on serial module commands.
character at the top of the FIFO.
ERR = 0 must be used to get the correct A/D flag information
when in multidrop mode.
