18.3
In Synchronous Master mode, the data is transmitted in
a half-duplex manner (i.e., transmission and reception
do not occur at the same time). When transmitting data,
the reception is inhibited and vice versa. Synchronous
mode is entered by setting bit SYNC (TXSTAx<4>). In
addition, enable bit SPEN (RCSTAx<7>) is set in order
to configure the appropriate I/O pins to CK (clock) and
DT (data) lines, respectively. The Master mode indi-
cates that the processor transmits the master clock on
the CK line. The Master mode is entered by setting bit
CSRC (TXSTAx<7>).
18.3.1
The USART transmitter block diagram is shown in
Figure 18-1. The heart of the transmitter is the Transmit
(Serial) Shift Register (TSR). The shift register obtains
its data from the Read/Write Transmit Buffer register,
TXREG. The TXREGx register is loaded with data in
software. The TSR register is not loaded until the last
bit has been transmitted from the previous load. As
soon as the last bit is transmitted, the TSR is loaded
with new data from the TXREGx (if available). Once the
TXREGx register transfers the data to the TSR register
(occurs in one T
interrupt bit TXxIF (PIR1<4> for USART1, PIR3<4> for
USART2) is set. The interrupt can be enabled/disabled
by setting/clearing enable bit TXxIE (PIE1<4> for
USART1, PIE3<4> for USART2). Flag bit TXxIF will be

x = unknown, – = unimplemented, read as ‘0’. Shaded cells are not used for synchronous master transmission.

set, regardless of the state of enable bit TXxIE and can-
not be cleared in software. It will reset only when new
data is loaded into the TXREGx register. While flag bit
TXxIF indicates the status of the TXREGx register,
another bit TRMT (TXSTAx<1>) shows the status of the
TSR register. TRMT is a read-only bit, which is set
when the TSR is empty. No interrupt logic is tied to this
bit, so the user has to poll this bit in order to determine
if the TSR register is empty. The TSR is not mapped in
data memory, so it is not available to the user.

Note:
Initialize the SPBRG register for the appropriate
baud rate (Section 18.1 “USART Baud Rate
Generator (BRG)”).
Enable the synchronous master serial port by
setting bits SYNC, SPEN and CSRC.
If interrupts are desired, set enable bit TXxIE in
the appropriate PIE register.
If 9-bit transmission is desired, set bit TX9.
Enable the transmission by setting bit TXEN.
If 9-bit transmission is selected, the ninth bit
should be loaded in bit TX9D.
Start transmission by loading data to the
TXREGx register.
