: Specifies N + (16-K)/16 division function.
N + (16-K)/16 division function can only be used in the UART mode.
: Specifies the baud rate generator input clock.
: Specifies division ratio “N”.
: Specifies K for the “N+(16-K)/16” division.
The division ratio of the baud rate generator can be specified in the registers shown above.
Table 9-6 lists the settings of baud rate generator division ratio.
Table 9-6 Setting division ratio
BR0ADDE=0 BR0ADDE=1 (Note 1)
(Only UART)
BR0S Specify “N” (Note 2) (Note 3)
BR0K No setting required Setting “K” (Note 4)
Division ratio Divide by N N + (16 − K) division
