NO COMMAND
鈥�
001
RESET MODE
REGISTER POINTER
Causes the mode register pointer to point to UMR1n.
010
RESET RECEIVER
Immediately disables the receiver, clears USRn[FFULL,RXRDY], and reinitializes
the receiver FIFO pointer. No other registers are altered. Because it places the
receiver in a known state, use this command instead of RECEIVER DISABLE when
reconfiguring the receiver.
011
RESET
TRANSMITTER
Immediately disables the transmitter and clears USRn[TXEMP,TXRDY]. No other
registers are altered. Because it places the transmitter in a known state, use this
command instead of TRANSMITTER DISABLE when reconfiguring the transmitter.
100
RESET ERROR
STATUS
Clears USRn[RB,FE,PE,OE]. Also used in block mode to clear all error bits after
a data block is received.
101
RESET BREAK
鈥�
CHANGE INTERRUPT
Clears the delta break bit, UISRn[DB].
110
START BREAK
Forces UTXDn low. If the transmitter is empty, break may be delayed up to one bit
time. If the transmitter is active, break starts when character transmission
completes. Break is delayed until any character in the transmitter shift register is
sent. Any character in the transmitter holding register is sent after the break.
Transmitter must be enabled for the command to be accepted. This command
ignores the state of UCTSn.
111
STOP BREAK
Causes UTXDn to go high (mark) within two bit times. Any characters in the
transmit buffer are sent.
