14.3.2
Baud rates are generated by the baud generator.
The baud rate generator generates a baud rate by counting the clock selected by the baud rate clock selection bits
(U0CK1, U0CK0) of the UART0 mode register 0 (UA0MOD0). The count value of the baud rate generator can be set
by writing it in the UART0 baud rate register H or L (UA0BRTH, UA0BRTL). The maximum count is 4096.
The setting values of UA0BRTH and UA0BRTL are expressed by the following equation.
Table 14-2 lists the count values for typical baud rates.
Note:
- When UA0BRTH or UA0BRTL is set to a value equal to less than “0007H”, the value set is read from UA0BRTH or
UA0BRTL but the value of the baud rate clock counter is the same as the value when UA0BRTH or UA0BRTL is set
to “0008H”.
- When specifying 65.536 kHz (LSCLK×2) for the clock, enable the operation of the 2×low-speed clock by setting bit 2
(ENMLT) of the frequency control register 1 (FCON1) to “1”.
- Compensating tolerant of RC oscillation 500kHz with Timer can support errors of +/- 2% or less at 9600bps. See
Section 10.3.2., “Frequency measurement mode”.
