Serial Interface (layer-1 functions)
Selectable Enhanced Resolution Baud Rate Generator (V3.x)
Two features are provided to allow the ESCC2 to work with higher XTAL rates and
support higher transmission baud rates. The first is XTAL clock divide-by-4 logic and the
second is the enhanced Baud Rate Generator (see also the BRG register description).
XTAL1-2 clock divide-by-4 function may optionally be selected (CCR4:MCK4) to feed
the core logic and timer blocks. This allows the device to function with XTAL frequency
up to 33 MHz. The baud rate generator is fed directly from the XTAL. It also allows the
timer block to operate at the highest resolution. See also description for CCR4 and TIMR
registers.
The enhanced baud rate generator has two modes of operation for added flexibility. The
normal mode is as in previous versions of the device. For the enhanced mode, the
Baud Rate generator bits BR0 … BR9 are re-assigned to provide two stages of division.
The first stage divides the clock by integer number up to 63, whereas the second stage
allows further division by powers of 2 (1, 2, 4, 8, 16, 32, 64, …, 32768). See also
description of the BRG register.
The Appendix shows baud rates derived from typical XTAL frequencies using the two
modes of the baud rate generator.
