SERIAL COMMUNICATIONS INTERFACE (Cont’d)
DATA REGISTER (DR)
Read/Write
Reset Value: Undefined
Contains the Received or Transmitted data char-
acter, depending on whether it is read from or writ-
ten to.
The Data register performs a double function (read
and write) since it is composed of two registers,
one for transmission (TDR) and one for reception
(RDR).
The TDR register provides the parallel interface
between the internal bus and the output shift reg-
ister (see Figure 1.).
The RDR register provides the parallel interface
between the input shift register and the internal
bus (see Figure 1.).
BAUD RATE REGISTER (BRR)
Read/Write
Reset Value: 00xx xxxx (XXh)
Bit 7:6= SCP[1:0]
First SCI Prescaler
These 2 prescaling bits allow several standard
clock division ranges:
Bit 5:3 = SCT[2:0]
SCI Transmitter rate divisor
These 3 bits, in conjunction with the SCP1 & SCP0
bits define the total division applied to the bus
clock to yield the transmit rate clock in convention-
al Baud Rate Generator mode.
Note: this TR factor is used only when the ETPR
fine tuning factor is equal to 00h; otherwise, TR is
replaced by the ETPR dividing factor.
Bit 2:0 = SCR[2:0]
SCI Receiver rate divisor.
These 3 bits, in conjunction with the SCP1 & SCP0
bits define the total division applied to the bus
clock to yield the receive rate clock in conventional
Baud Rate Generator mode.
Note: this RR factor is used only when the ERPR
fine tuning factor is equal to 00h; otherwise, RR is
replaced by the ERPR dividing factor.
