PT—Parity Type
B/C1–B/C0—Bits per Character
6.4.1.2 MODE REGISTER 2 (DUMR2). DUMR2 controls some of the serial module
configuration. It is accessed when the channel A mode register pointer points to DUMR2,
which ocurs after any access to DUMR1. Accesses to DUMR2 do not change the pointer.
CM1–CM0—Channel Mode
These bits select a channel mode as listed in Table 6-3. See 6.3.3 Looping Modes for
more information on the individual modes.
6-20
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 6-1 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 6-2 does not include start, parity, or stop bits.
