Note:
Table 59.
Bits 5:3 = SCT[2:0] SCI Transmitter rate divisor
Table 60.
This TR factor is used only when the ETPR fine tuning factor is equal to 00h; otherwise, TR
is replaced by the (TR*ETPR) dividing factor.
Bits 2:0 = SCR[2:0] SCI Receiver rate divisor.
Table 61.
These 3 bits, in conjunction with the SCP1 and SCP0 bits define the total division
applied to the bus clock to yield the transmit rate clock in conventional baud rate
Generator mode.
These 3 bits, in conjunction with the SCP1 and SCP0 bits define the total division
applied to the bus clock to yield the receive rate clock in conventional Baud Rate
Generator mode.
