36.8.4 Baud rate register (USARTx_BRR)
This register can only be written when the USART is disabled (UE=0). It may be
automatically updated by hardware in auto baud rate detection mode.
Address offset: 0x0C
Reset value: 0x0000
36.8.5 Guard time and prescaler register (USARTx_GTPR)
Address offset: 0x10
Reset value: 0x0000

Bits 31:16 Reserved, must be kept at reset value.
Bits 15:4 BRR[15:4]
BRR[15:4] = USARTDIV[15:4]
Bits 3:0 BRR[3:0]
When OVER8 = 0, BRR[3:0] = USARTDIV[3:0].
When OVER8 = 1:
BRR[2:0] = USARTDIV[3:0] shifted 1 bit to the right.
BRR[3] must be kept cleared.
