Mode 0: 8-Bit Shift Register Mode
Mode 0 is selected by clearing both the SM0 and SM1 bits in the
SFR SCON. Serial data enters and exits through RxD. TxD
outputs the shift clock. Eight data bits are transmitted or
received. Transmission is initiated by any instruction that writes
to SBUF. The data is shifted out of the RxD line. The eight bits
are transmitted with the least-significant bit (LSB) first, as
shown in Figure 52.
Rev. A | Page 54 of 72
Reception is initiated when the receive enable bit (REN) is 1
and the receive interrupt bit (RI) is 0. When RI is cleared the
data is clocked into the RxD line and the clock pulses are output
from the TxD line.
Mode 1: 8-Bit UART, Variable Baud Rate
Mode 1 is selected by clearing SM0 and setting SM1. Each data
byte (LSB first) is preceded by a start bit (Bit 0) and followed by
a stop bit (Bit 1). Therefore 10 bits are transmitted on TxD or
received on RxD. The baud rate is set by the Timer 1 or Timer 2
overflow rate, or a combination of the two (one for transmission
and the other for reception).
Transmission is initiated by writing to SBUF. The write-to-
SBUF signal also loads a 1 (stop bit) into the ninth bit position
of the transmit shift register. The data is output bit by bit until
the stop bit appears on TxD and the transmit interrupt flag (TI)
is automatically set as shown in Figure 51.
Reception is initiated when a 1-to-0 transition is detected on
RxD. Assuming a valid start bit was detected, character
reception continues. The start bit is skipped and the eight data
bits are clocked into the serial port shift register. When all eight
bits have been clocked in, the following events occur:
The eight bits in the receive shift register are latched into
SBUF.
The ninth bit (stop bit) is clocked into RB8 in SCON. The
receiver interrupt flag (RI) is set if, and only if, the
following conditions are met at the time the final shift
pulse is generated:
o
RI = 0
o
Either SM2 = 0 or SM2 = 1 and
the received stop bit = 1
If either of these conditions is not met, the received frame
is irretrievably lost, and RI is not set.
