BR2–BR0 — Baud Rate Select
These three bits select one of eight clock rates as the master clock
when the module is in master mode.
Since this master clock is derived the CPU bus clock, the user
program should not execute the WAIT instruction when the DDC
module in master mode. This will cause the SDA and SCL lines to
hang, as the WAIT instruction places the MCU in WAIT mode, with
CPU clock is halted. These bits are cleared upon reset. (See
15-2 . Baud Rate
NOTE:
CPU bus clock is external clock ÷ 4 = 6MHz
