Baud Rate, bits 7 … 0
The Baud Rate generator divisor consists of bits BR0-7 from BRG
register and bits BR8-9 from the CCR2 register.
The baud rate generator has two modes of operation giving added
flexibility.
Standard Mode:
bits BR9-0 give a value N (N = 0 … 1023) to give a XTAL clock
division factor k:
k = (N + 1)
Enhanced Mode: (version 3.x upwards)
This consists of a 2 stage divider. The first stage is divisor N is
determined by bits BR5-BR0 (N = 0 … 63) while the second stage
divisor M is determined by bit BR9 … BR6 (M = 0 … 15). The first
stage divides the clock by integer number up to 63, where the
second stage allows further division by powers of 2 (1, 2, 4, 8, 16,
32, 64, 128, …, 32768).
Division by 1 using M = ‘0’ is restricted to frequencies below
10 MHz (to be characterized). The XTAL clock division factor k:
k = (N + 1)
The Baud Rate generator is typically used to derive clocks for DTE
or DCE asynchronous baud rates with 16- oversampling mode.
Appendix A shows baud rates derived from typical XTAL
frequencies using the two modes of the baud rate generator for
ASYNC operation with 16- oversampling enabled.
