Function

UARTi Baud Rate Register (i=0 to 4)(1, 2, 3)

Setting Range

Symbol

Address

After Reset

U0BRG to U4BRG 036916, 02E916, 033916, 032916, 02F916

Indeterminate

If the setting value is m, the UiBRG register

divides a count source by m+1

0016 to FF16

NOTES:

1. Use the MOV instruction to set the UiBRG register.

2. Set the UiBRG register data transmit and receive is stopped.

3. Set the UiBRG register after setting the CLK1 and CLK0 bits in the UiC0 register.
