Several issues on STM32U0, STM32F0 and STM32G0 references manuals.

[AA1]

I found more issues.

1. Missing SRAMEN bit in RCC_AHBENR register. I think it is bit 9. See STM32U0 RM0503 page 54, RCC_AHBSMENR register and STM32F0 RM0091. With this new bit, reset value is: 0x0000 0300
Also I think that it is missing SRAMRST bit in RCC_AHBRSTR register. It should be bit 9.

This problem is also on STM32G0 and STM32C0 RMs.

2. Missing TIMx_OR2 and TIMx_OR3 registers mentioned on RM0503 page 553.
This problem is also on STM32G0 RM0444 and RM0454, and STM32C0 RM0490.

3. STM32F0 RM0091 didn't mention how internal break input (called "Internal break event sources") is selected. See pages 359 and 514. STM32F0 RM0091 doesn't have an equivalent to STM32U0 RM0503 figure 164 on page 592.

4. STM32U0 RM0503 pages 107, 108 and 118, mentions pin PE6 but it doesn't exist in datasheet. RTC_TAMP3/TAMP_IN3 is pin PB15 and not pin PE6.

From STM32U0 DS:
TAMP_IN1 PC13
TAMP_IN2 PA0
TAMP_IN3 PB15
TAMP_IN4 PC5
TAMP_IN5 PA1

5. STM32U0 RM0503 page 413: Missing description of VREFBUF_CCR register Bits 5:0. See the same register on STM32G0 RM.

6. STM32F0 RM0091 page 625 has a typo: Missing a space in RTC_TAMP3input.
