RC1–RC0—Receiver Commands
6-28
No Action Taken—The no action taken command causes the transmitter to stay in its
current mode. If the transmitter is enabled, it remains enabled; if disabled, it remains
disabled.
Transmitter Enable—The transmitter enable command enables operation of the
channel's transmitter. The TxEMP and TxRDY bits in the DUSR are also set. If the
transmitter is already enabled, this command has no effect.
Transmitter Disable—The transmitter disable command terminates transmitter operation
and clears the TxEMP and TxRDY bits in the DUSR. However, if a character is being
transmitted when the transmitter is disabled, the transmission of the character is
completed before the transmitter becomes inactive. If the transmitter is already
disabled, this command has no effect.
Do Not Use—Do not use this bit combination because the result is indeterminate.
These bits select a single command as listed in Table 6-9.
No Action Taken—The no action taken command causes the receiver to stay in its
current mode. If the receiver is enabled, it remains enabled; if disabled, it remains
disabled.
Receiver Enable—The receiver enable command enables operation of the channel's
receiver. If the serial module is not in multidrop mode, this command also forces the
receiver into the search-for-start-bit state. If the receiver is already enabled, this
command has no effect.
Receiver Disable—The receiver disable command disables the receiver immediately.
Any character being received is lost. The command has no effect on the receiver status
bits or any other control register. If the serial module is programmed to operate in the
