Document error: RM0090 Rev 21

Hello,

Document: RM0090 Reference Manual for STM32F405/415, STM32F407/417, STM32F427/437 and
STM32F429/439.

https://www.st.com/resource/en/reference_manual/rm0090-stm32f405415-stm32f407417-stm32f427437-and-stm32f429439-advanced-armbased-32bit-mcus-stmicroelectronics.pdf

Revision: 21, 07-Jun-2024.

Location: Pages 847-862 in Section 27. Also, Figure 241, 242, 243, 244, 245, Table 125.

This section, figures and table all contain 17 references to ITEVFEN bit, supposedly from I2_CR2 control register.
In reality, there is no such bit in this register, the actual name is ITEVTEN (interrupt event enable), and it is located in I2C_CR2, bit 9.

Section 27.6.2 has correct name.

stm32f405xx.h file, and others related to i2c, use the correct name:

 

#define I2C_CR2_ITEVTEN_Pos (9U)
#define I2C_CR2_ITEVTEN_Msk (0x1UL << I2C_CR2_ITEVTEN_Pos) /*!< 0x00000200 */
#define I2C_CR2_ITEVTEN I2C_CR2_ITEVTEN_Msk /*!<Event Interrupt Enable */

Therefore, the ITEVFEN in the document should be replaced with ITEVTEN.

 

Thank you

Hello @Zman552625 and welcome to the ST community,

I'm escalating this internally for analysis and fix.

Thank you for your collaboration.
