NOTES TO TABLES 10 AND 11:
1. Tables 6 and 7 apply to UART modes 1 and 3 (variable rate modes), and show CPU clock rates in MHz for standard baud rates.
2. Table 6 shows timer settings and CPU clock rates with the SMOD1 bit in the PCON register = 0 (the default after reset), while Table 7
reflects the SMOD1 bit = 1.
3. The tables show all potential CPU clock frequencies up to 10 MHz that may be used for baud rates. Other CPU clock frequencies that would
give only lower baud rates are not shown.
4. Table entries marked with an asterisk (*) indicate standard crystal and ceramic resonator frequencies that may be obtained from many
sources without special ordering.
