Figure 90. SCI baud rate and extended prescaler block diagram
Conventional baud rate generation
The baud rates for the receiver and transmitter (Rx and Tx) are set independently and
calculated as follows
with:
PR = 1, 3, 4 or 13 (see SCP[1:0] bits)
TR = 1, 2, 4, 8, 16, 32, 64, 128
(see SCT[2:0] bits)
