P89LPC932A1
8-bit microcontroller with accelerated two-clock 80C51 core
7.20.3 Mode 2
11 bits are transmitted (through TXD) or received (through RXD): start bit (logic 0), 8 data
bits (LSB rst), a programmable 9th data bit, and a stop bit (logic 1). When data is
transmitted, the 9th data bit (TB8 in SCON) can be assigned the value of logic 0 or logic 1.
Or, for example, the parity bit (P, in the PSW) could be moved into TB8. When data is
received, the 9th data bit goes into RB8 in Special Function Register SCON, while the stop
bit is not saved. The baud rate is programmable to either 1
16 or
1
32 of the CPU clock
frequency, as determined by the SMOD1 bit in PCON.
7.20.4 Mode 3
11 bits are transmitted (through TXD) or received (through RXD): a start bit (logic 0), 8
data bits (LSB rst), a programmable 9th data bit, and a stop bit (logic 1). In fact, Mode 3 is
the same as Mode 2 in all respects except baud rate. The baud rate in Mode 3 is variable
and is determined by the Timer 1 overow rate or the Baud Rate Generator (described in
7.20.5 Baud rate generator and selection
The P89LPC932A1 enhanced UART has an independent Baud Rate Generator. The baud
rate is determined by a baud-rate preprogrammed into the BRGR1 and BRGR0 SFRs
which together form a 16-bit baud rate divisor value that works in a similar manner as
Timer 1 but is much more accurate. If the baud rate generator is used, Timer 1 can be
used for other timing functions.
The UART can use either Timer 1 or the baud rate generator output (see Figure 13). Note
that Timer T1 is further divided by 2 if the SMOD1 bit (PCON.7) is cleared. The
independent Baud Rate Generator uses OSCCLK.
7.20.6 Framing error
Framing error is reported in the status register (SSTAT). In addition, if SMOD0 (PCON.6)
is logic 1, framing errors can be made available in SCON.7 respectively. If SMOD0 is
logic 0, SCON.7 is SM0. It is recommended that SM0 and SM1 (SCON.7:6) are set up
when SMOD0 is logic 0.
7.20.7 Break detect
Break detect is reported in the status register (SSTAT). A break is detected when
11 consecutive bits are sensed LOW. The break detect can be used to reset the device
and force the device into ISP mode.
