Function
Baud Rate Generator Control Register (HBR0CR)
Baud Rate Generator Control Register 2 (HBR0ADD)
Sets divide ratio “N” of the baud rate generator.
Specifies K for the "N + (16 - K)/16" division.
“Write
"0."
Enables or disables N+(16-K)/16 division function.
This function is available only for UART mode.
Always reads "0."
