AT89C5130A/31A-M

Example of computed value when X2 = 1, SMOD1 = 1, SPD = 1

Example of computed value when X2 = 0, SMOD1 = 0, SPD = 0

The baud rate generator can be used for mode 1 or 3 (refer to Figure 15-4.), but also for mode 0

for UART, thanks to the bit SRC located in BDRCON register (Table 15-4.)
