STMicroelectronics /STM32U073 /USART1 /USART_PRESC

Clock prescaler The USART input clock can be divided by a prescaler factor: Remaining combinations: Reserved Note: When PRESCALER is programmed with a value different of the allowed ones, programmed prescaler value is equal to 1011 i.e. input clock divided by 256.

0 (B_0x0): input clock not divided

1 (B_0x1): input clock divided by 2

2 (B_0x2): input clock divided by 4

3 (B_0x3): input clock divided by 6

4 (B_0x4): input clock divided by 8

5 (B_0x5): input clock divided by 10

6 (B_0x6): input clock divided by 12

7 (B_0x7): input clock divided by 16

8 (B_0x8): input clock divided by 32

9 (B_0x9): input clock divided by 64
