35.20.8 UxBRG

UART Baud Rate Generator
Note:
  1. The individual bytes in this multibyte register can be accessed with the following register names:
    • UxBRGH: Accesses the high byte BRG[15:8]
    • UxBRGL: Accesses the low byte BRG[7:0]
  2. The UxBRG registers will only be written when ON = 0.
  3. Maximum BRG value when MODE = ‘100x and BRGS = 1 is 0x7FFE.
  4. Maximum BRG value when MODE = ‘100x and BRGS = 0 is 0x1FFE.

Bits 15:0 – BRG[15:0] Baud Rate Generator Value

The UART Baud Rate equals [Fosc*(1+(BRGS*3)]/[(16*(BRG+1))]
The individual bytes in this multibyte register can be accessed with the following register names: UxBRGH: Accesses the high byte BRG[15:8] UxBRGL: Accesses the low byte BRG[7:0] The UxBRG registers will only be written when ON = 0. Maximum BRG value when MODE = ‘100x and BRGS = 1 is 0x7FFE. Maximum BRG value when MODE = ‘100x and BRGS = 0 is 0x1FFE.
