16.2
16.2.1
The UART module is enabled by setting the UARTEN
bit in the UxMODE register (where x = 1 or 2). Once
enabled, the UxTX and UxRX pins are configured as an
output and an input respectively, overriding the TRIS
and LATCH register bit settings for the corresponding
I/O port pins. The UxTX pin is at logic ‘1’ when no
transmission is taking place.
16.2.2
The UART module is disabled by clearing the UARTEN
bit in the UxMODE register. This is the default state
after any Reset. If the UART is disabled, all I/O pins
operate as port pins under the control of the latch and
TRIS bits of the corresponding port pins.
Disabling the UART module resets the buffers to empty
states. Any data characters in the buffers are lost and
the baud rate counter is reset.
All error and status flags associated with the UART
module are reset when the module is disabled. The
URXDA, OERR, FERR, PERR, UTXEN, UTXBRK and
UTXBF bits are cleared, whereas RIDLE and TRMT
are set. Other control bits, including ADDEN,
URXISEL<1:0>, UTXISEL, as well as the UxMODE
and UxBRG registers, are not affected.
Clearing the UARTEN bit while the UART is active will
abort all pending transmissions and receptions and
reset the module as defined above. Reenabling the
UART will restart the UART in the same configuration.
16.2.3
Control bits PDSEL<1:0> in the UxMODE register are
used to select the data length and parity used in the
transmission. The data length may either be 8 bits with
even, odd or no parity, or 9 bits with no parity.
The STSEL bit determines whether one or two Stop bits
will be used during data transmission.
The default (power-on) setting of the UART is 8 bits, no
parity and 1 Stop bit (typically represented as 8, N, 1).

16.3
16.3.1
The following steps must be performed in order to
transmit 8-bit data:
1.
2.
3.
4.
5.
16.3.2
The sequence of steps involved in the transmission of
9-bit data is similar to 8-bit transmission, except that a
16-bit data word (of which the upper 7 bits are always
clear) must be written to the UxTXREG register.
16.3.3
The transmit buffer is 9 bits wide and 4 characters
deep. Including the Transmit Shift register (UxTSR),
the user effectively has a 5-deep FIFO (First-In, First-
Out) buffer. The UTXBF Status bit (UxSTA<9>)
indicates whether the transmit buffer is full.
If a user attempts to write to a full buffer, the new data
will not be accepted into the FIFO, and no data shift will
occur within the buffer. This enables recovery from a
buffer overrun condition.
The FIFO is reset during any device Reset but is not
affected when the device enters or wakes up from a
Power-Saving mode.
dsPIC30F5011/5013
Set up the UART:
First, the data length, parity and number of Stop
bits must be selected. Then, the transmit and
receive interrupt enable and priority bits are
setup in the UxMODE and UxSTA registers.
Also, the appropriate baud rate value must be
written to the UxBRG register.
Enable the UART by setting the UARTEN bit
(UxMODE<15>).
Set the UTXEN bit (UxSTA<10>), thereby
enabling a transmission.
Write the byte to be transmitted to the lower byte
of UxTXREG. The value will be transferred to the
Transmit Shift register (UxTSR) immediately
and the serial bit stream will start shifting out
during the next rising edge of the baud clock.
Alternatively, the data byte may be written while
UTXEN = 0, following which, the user may set
UTXEN. This will cause the serial bit stream to
begin immediately because the baud clock will
start from a cleared state.
A transmit interrupt will be generated, depend-
ing on the value of the interrupt control bit
UTXISEL (UxSTA<15>).
