Function
Baud Rate Generator Control Register (BR0CR)
Baud Rate Generator Control Register 2 (BR0ADD)
Sets divide ratio “N” of the baud rate generator.
Specifies K for the "N + (16 - K)/16" division.
Selects input clock to the baud rate generator.
Enables or disables N+(16-K)/16 division function.
This function is available only for UART mode.
“Write "0."
Always reads "0."
